ANDROID: vendor_hooks: Add hooks for __alloc_pages_direct_reclaim
Provide a vendor hook to allow drain_all_pages to be skipped during direct reclaim in some cases to avoid delays caused by it in cases when the benefits of draining pcp lists are known to be small.

FROMGIT: mm: count time in drain_all_pages during direct reclaim as memory pressure
When page allocation in direct reclaim path fails, the system will make
one attempt to shrink per-cpu page lists and free pages from high alloc
reserves. Draining per-cpu pages into buddy allocator can be a very slow
operation because it's done using workqueues and the task in direct
reclaim waits for all of them to finish before proceeding. Currently this
time is not accounted as psi memory stall.
While testing mobile devices under extreme memory pressure, when
allocations are failing during direct reclaim, we notices that psi events
which would be expected in such conditions were not triggered. After
profiling these cases it was determined that the reason for missing psi
events was that a big chunk of time spent in direct reclaim is not
accounted as memory stall, therefore psi would not reach the levels at
which an event is generated. Further investigation revealed that the bulk
of that unaccounted time was spent inside drain_all_pages call.
A typical captured case when drain_all_pages path gets activated:
__alloc_pages_slowpath took 44.644.613ns
__perform_reclaim took 751.668ns (1.7%)
drain_all_pages took 43.887.167ns (98.3%)
PSI in this case records the time spent in __perform_reclaim but ignores
drain_all_pages, IOW it misses 98.3% of the time spent in
__alloc_pages_slowpath.
Annotate __alloc_pages_direct_reclaim in its entirety so that delays from
handling page allocation failure in the direct reclaim path are accounted
as memory stall.

mm/page_alloc: speed up the iteration of max_order
commit 7ad69832f37e3cea8557db6df7c793905f1135e8 upstream.
When we free a page whose order is very close to MAX_ORDER and greater
than pageblock_order, it wastes some CPU cycles to increase max_order to
MAX_ORDER one by one and check the pageblock migratetype of that page
repeatedly especially when MAX_ORDER is much larger than pageblock_order.
We also should not be checking migratetype of buddy when "order ==
MAX_ORDER - 1" as the buddy pfn may be invalid, so adjust the condition.
With the new check, we don't need the max_order check anymore, so we
replace it.
Also adjust max_order initialization so that it's lower by one than
previously, which makes the code hopefully more clear.

mm/page_alloc: fix memory map initialization for descending nodes
commit 122e093c1734361dedb64f65c99b93e28e4624f4 upstream. On systems with memory nodes sorted in descending order, for instance Dell Precision WorkStation T5500, the struct pages for higher PFNs and respectively lower nodes, could be overwritten by the initialization of struct pages corresponding to the holes in the memory sections. For example for the below memory layout [ 0.245624] Early memory node ranges [ 0.248496] node 1: [mem 0x0000000000001000-0x0000000000090fff] [ 0.251376] node 1: [mem 0x0000000000100000-0x00000000dbdf8fff] [ 0.254256] node 1: [mem 0x0000000100000000-0x0000001423ffffff] [ 0.257144] node 0: [mem 0x0000001424000000-0x0000002023ffffff] the range 0x1424000000 - 0x1428000000 in the beginning of node 0 starts in the middle of a section and will be considered as a hole during the initialization of the last section in node 1. The wrong initialization of the memory map causes panic on boot when CONFIG_DEBUG_VM is enabled. Reorder loop order of the memory map initialization so that the outer loop will always iterate over populated memory regions in the ascending order and the inner loop will select the zone corresponding to the PFN range. This way initialization of the struct pages for the memory holes will be always done for the ranges that are actually not populated.

ANDROID: mm, kasan: fix for "integrate page_alloc init with HW_TAGS"
My commit "integrate page_alloc init with HW_TAGS" changed the order of
kernel_unpoison_pages() and kernel_init_free_pages() calls. This leads
to complaints from the page unpoisoning code, as the poison pattern gets
overwritten for __GFP_ZERO allocations.
Fix by restoring the initial order. Also add a warning comment.

ANDROID: mm: cma: skip problematic pageblock
alloc_contig_range is supposed to work on max(MAX_ORDER_NR_PAGES, or pageblock_nr_pages) granularity aligned range. If it fails at a page and return error to user, user doesn't know what page makes the allocation failure and keep retrying another allocation with new range including the failed page and encountered error again and again until it could escape the out of the granularity block. Instead, let's make CMA aware of what pfn was troubled in previous trial and then continue to work new pageblock out of the failed page so it doesn't see the repeated error repeatedly. Currently, this option works for only __GFP_NORETRY case for safe for existing CMA users.

ANDROID: mm: do not try test_page_isoalte if migration fails
Currently, alloc_contig_range expects that even though a page fails with -EBUSY from __alloc_contig_migrate_range, it want to check those failed pages in test_pages_isolated again with hope that those page would be freed soon so cma allocatoin would be succeeded. However, it depends on the luck and I found sometimes test_page_isolated constantly fails at the page repeatedly whenever cma_alloc retried. Rather than burning out CPU to check the page's status in test_pages_isolated for GFP_NORETRY allocation, just bail out and relies on the user what they want to do. Currently, this option works for only __GFP_NORETRY case for safe of existing other users.

ANDROID: mm: add cma allocation statistics
alloc_contig_range is the core worker function for CMA allocation so it has every information to be able to understand allocation latency. For example, how many pages are migrated, how many time unmap was needed to migrate pages, how many times it encountered errors by some reasons. This patch adds such statistics in the alloc_contig_range and return it to user so user can use those information to analyize latency. The cma_alloc is first user for the statistics, which export the statistics as new trace event(i.e., cma_alloc_info). It was really usefuli to optimize cma allocation work.

UPSTREAM: mm, page_alloc: move draining pcplists to page isolation users
Currently, pcplists are drained during set_migratetype_isolate() which means once per pageblock processed start_isolate_page_range(). This is somewhat wasteful. Moreover, the callers might need different guarantees, and the draining is currently prone to races and does not guarantee that no page from isolated pageblock will end up on the pcplist after the drain. Better guarantees are added by later patches and require explicit actions by page isolation users that need them. Thus it makes sense to move the current imperfect draining to the callers also as a preparation step.

mm: page_alloc: refactor setup_per_zone_lowmem_reserve()
[ Upstream commit 470c61d70299b1826f56ff5fede10786798e3c14 ] setup_per_zone_lowmem_reserve() iterates through each zone setting zone->lowmem_reserve[j] = 0 (where j is the zone's index) then iterates backwards through all preceding zones, setting lower_zone->lowmem_reserve[j] = sum(managed pages of higher zones) / lowmem_reserve_ratio[idx] for each (where idx is the lower zone's index). If the lower zone has no managed pages or its ratio is 0 then all of its lowmem_reserve[] entries are effectively zeroed. As these arrays are only assigned here and all lowmem_reserve[] entries for index < this zone's index are implicitly assumed to be 0 (as these are specifically output in show_free_areas() and zoneinfo_show_print() for example) there is no need to additionally zero index == this zone's index too. This patch avoids zeroing unnecessarily. Rather than iterating through zones and setting lowmem_reserve[j] for each lower zone this patch reverse the process and populates each zone's lowmem_reserve[] values in ascending order. This clarifies what is going on especially in the case of zero managed pages or ratio which is now explicitly shown to clear these values.

BACKPORT: FROMGIT: kasan: disable freed user page poisoning with HW tags
Poisoning freed pages protects against kernel use-after-free. The likelihood of such a bug involving kernel pages is significantly higher than that for user pages. At the same time, poisoning freed pages can impose a significant performance cost, which cannot always be justified for user pages given the lower probability of finding a bug. Therefore, disable freed user page poisoning when using HW tags. We identify "user" pages via the flag set GFP_HIGHUSER_MOVABLE, which indicates a strong likelihood of not being directly accessible to the kernel.

BACKPORT: FROMGIT: arm64: mte: handle tags zeroing at page allocation time
Currently, on an anonymous page fault, the kernel allocates a zeroed
page and maps it in user space. If the mapping is tagged (PROT_MTE),
set_pte_at() additionally clears the tags. It is, however, more
efficient to clear the tags at the same time as zeroing the data on
allocation. To avoid clearing the tags on any page (which may not be
mapped as tagged), only do this if the vma flags contain VM_MTE. This
requires introducing a new GFP flag that is used to determine whether
to clear the tags.
The DC GZVA instruction with a 0 top byte (and 0 tag) requires
top-byte-ignore. Set the TCR_EL1.{TBI1,TBID1} bits irrespective of
whether KASAN_HW is enabled.

FROMGIT: kasan: use separate (un)poison implementation for integrated init
Currently with integrated init page_alloc.c needs to know whether kasan_alloc_pages() will zero initialize memory, but this will start becoming more complicated once we start adding tag initialization support for user pages. To avoid page_alloc.c needing to know more details of what integrated init will do, move the unpoisoning logic for integrated init into the HW tags implementation. Currently the logic is identical but it will diverge in subsequent patches. For symmetry do the same for poisoning although this logic will be unaffected by subsequent patches.

UPSTREAM: mm: page_alloc: ignore init_on_free=1 for debug_pagealloc=1
On !ARCH_SUPPORTS_DEBUG_PAGEALLOC (like ia64) debug_pagealloc=1 implies
page_poison=on:
if (page_poisoning_enabled() ||
(!IS_ENABLED(CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC) &&
debug_pagealloc_enabled()))
static_branch_enable(&_page_poisoning_enabled);
page_poison=on needs to override init_on_free=1.
Before the change it did not work as expected for the following case:
- have PAGE_POISONING=y
- have page_poison unset
- have !ARCH_SUPPORTS_DEBUG_PAGEALLOC arch (like ia64)
- have init_on_free=1
- have debug_pagealloc=1
That way we get both keys enabled:
- static_branch_enable(&init_on_free);
- static_branch_enable(&_page_poisoning_enabled);
which leads to poisoned pages returned for __GFP_ZERO pages.
After the change we execute only:
- static_branch_enable(&_page_poisoning_enabled);
and ignore init_on_free=1.

mm/page_alloc: fix counting of free pages after take off from buddy
commit bac9c6fa1f929213bbd0ac9cdf21e8e2f0916828 upstream. Recently we found that there is a lot MemFree left in /proc/meminfo after do a lot of pages soft offline, it's not quite correct. Before Oscar's rework of soft offline for free pages [1], if we soft offline free pages, these pages are left in buddy with HWPoison flag, and NR_FREE_PAGES is not updated immediately. So the difference between NR_FREE_PAGES and real number of available free pages is also even big at the beginning. However, with the workload running, when we catch HWPoison page in any alloc functions subsequently, we will remove it from buddy, meanwhile update the NR_FREE_PAGES and try again, so the NR_FREE_PAGES will get more and more closer to the real number of available free pages. (regardless of unpoison_memory()) Now, for offline free pages, after a successful call take_page_off_buddy(), the page is no longer belong to buddy allocator, and will not be used any more, but we missed accounting NR_FREE_PAGES in this situation, and there is no chance to be updated later. Do update in take_page_off_buddy() like rmqueue() does, but avoid double counting if some one already set_migratetype_isolate() on the page. [1]: commit |

FROMLIST: mm: page_alloc: dump migrate-failed pages only at -EBUSY
alloc_contig_dump_pages() aims for helping debugging page migration failure by elevated page refcount compared to expected_count. (for the detail, please look at migrate_page_move_mapping) However, -ENOMEM is just the case that system is under memory pressure state, not relevant with page refcount at all. Thus, the dumping page list is not helpful for the debugging point of view.

ANDROID: mm: page_pinner: introduce failure_tracking feature
CMA allocation can fail by temporal page refcount increasement by get_page API as well as get_user_pages friends. However, since get_page is one of the most hot function, it is hard to hook get_page to get callstack everytime due to performance concern. Furthermore, get_page could be nested multiple times so we couldn't track all of the pin sites on limited space of page_pinner. Thus, here approach is keep tracking of put_page callsite rather than get_page once VM found the page migration failed. It's based on assumption: 1. Since it's temporal page refcount, it could be released soon before overflowing dmesg log buffer 2. developer can find the pair of get_page by reviewing put_page. By default, it's eanbled. If you want to disable it: echo 0 > $debugfs/page_pinner/failure_tracking You can capture the tracking using: cat $debugfs/page_pinner/alloc_contig_failed note: the example below is artificial: Page pinned ts 386067292 us count 0 PFN 10162530 Block 9924 type Isolate Flags 0x800000000008000c(uptodate|dirty|swapbacked) __page_pinner_migration_failed+0x30/0x104 putback_lru_page+0x90/0xac putback_movable_pages+0xc4/0x204 __alloc_contig_migrate_range+0x290/0x31c alloc_contig_range+0x114/0x2bc cma_alloc+0x2d8/0x698 cma_alloc_write+0x58/0xb8 simple_attr_write+0xd4/0x124 debugfs_attr_write+0x50/0xd8 full_proxy_write+0x70/0xf8 vfs_write+0x168/0x3a8 ksys_write+0x7c/0xec __arm64_sys_write+0x20/0x30 el0_svc_common+0xa4/0x180 do_el0_svc+0x28/0x88 el0_svc+0x14/0x24 Page pinned ts 385867394 us count 0 PFN 10162530 Block 9924 type Isolate Flags 0x800000000008000c(uptodate|dirty|swapbacked) __page_pinner_migration_failed+0x30/0x104 __alloc_contig_migrate_range+0x200/0x31c alloc_contig_range+0x114/0x2bc cma_alloc+0x2d8/0x698 cma_alloc_write+0x58/0xb8 simple_attr_write+0xd4/0x124 debugfs_attr_write+0x50/0xd8 full_proxy_write+0x70/0xf8 vfs_write+0x168/0x3a8 ksys_write+0x7c/0xec __arm64_sys_write+0x20/0x30 el0_svc_common+0xa4/0x180 do_el0_svc+0x28/0x88 el0_svc+0x14/0x24 el0_sync_handler+0x88/0xec el0_sync+0x198/0x1c0 Bug: 183414571 Signed-off-by: Minchan Kim <minchan@kernel.org> Signed-off-by: Minchan Kim <minchan@google.com> Change-Id: Ie79902c18390eb9f320d823839bb9d9a7fdcdb31 |

ANDROID: mm: introduce page_pinner
For CMA allocation, it's really critical to migrate a page but sometimes it fails. One of the reasons is some driver holds a page refcount for a long time so VM couldn't migrate the page at that time. The concern here is there is no way to find the who hold the refcount of the page effectively. This patch introduces feature to keep tracking page's pinner. All get_page sites are vulnerable to pin a page for a long time but the cost to keep track it would be significat since get_page is the most frequent kernel operation. Furthermore, the page could be not user page but kernel page which is not related to the page migration failure. So, this patch keeps tracking only get_user_pages/follow_page with (FOLL_GET|PIN friends because they are the very common APIs to pin user pages which could cause migration failure and the less frequent than get_page so runtime cost wouldn't be that big but could cover many cases effectively. This patch also introduces put_user_page API. It aims for attributing "the pinner releases the page from now on" while it release the page refcount. Thus, any user of get_user_pages/follow_page(FOLL_GET) must use put_user_page as pair of those functions. Otherwise, page_pinner will treat them long term pinner as false postive but nothing should affect stability. * $debugfs/page_pinner/threshold It indicates threshold(microsecond) to flag long term pinning. It's configurable(Default is 300000us). Once you write new value to the threshold, old data will clear. * $debugfs/page_pinner/longterm_pinner It shows call sites where the duration of pinning was greater than the threshold. Internally, it uses a static array to keep 4096 elements and overwrites old ones once overflow happens. Therefore, you could lose some information. example) Page pinned ts 76953865787 us count 1 PFN 9856945 Block 9625 type Movable Flags 0x8000000000080014(uptodate|lru|swapbacked) __set_page_pinner+0x34/0xcc try_grab_page+0x19c/0x1a0 follow_page_pte+0x1c0/0x33c follow_page_mask+0xc0/0xc8 __get_user_pages+0x178/0x414 __gup_longterm_locked+0x80/0x148 internal_get_user_pages_fast+0x140/0x174 pin_user_pages_fast+0x24/0x40 CCC BBB AAA __arm64_sys_ioctl+0x94/0xd0 el0_svc_common+0xa4/0x180 do_el0_svc+0x28/0x88 el0_svc+0x14/0x24 note: page_pinner doesn't guarantee attributing/unattributing are atomic if they happen at the same time.

ANDROID: implement wrapper for reverse migration
Reverse migration is used to do the balancing the occupancy of memory zones in a node in the system whose imabalance may be caused by migration of pages to other zones by an operation, eg: hotremove and then hotadding the same memory. In this case there is a lot of free memory in newly hotadd memory which can be filled up by the previous migrated pages(as part of offline/hotremove) thus may free up some pressure in other zones of the node.

mm/memcg: set memcg when splitting page
commit e1baddf8475b06cc56f4bafecf9a32a124343d9f upstream.
As described in the split_page() comment, for the non-compound high order
page, the sub-pages must be freed individually. If the memcg of the first
page is valid, the tail pages cannot be uncharged when be freed.
For example, when alloc_pages_exact is used to allocate 1MB continuous
physical memory, 2MB is charged(kmemcg is enabled and __GFP_ACCOUNT is
set). When make_alloc_exact free the unused 1MB and free_pages_exact free
the applied 1MB, actually, only 4KB(one page) is uncharged.
Therefore, the memcg of the tail page needs to be set when splitting a
page.
Michel:
There are at least two explicit users of __GFP_ACCOUNT with
alloc_exact_pages added recently. See

FROMGIT: kasan, mm: integrate page_alloc init with HW_TAGS
This change uses the previously added memory initialization feature of HW_TAGS KASAN routines for page_alloc memory when init_on_alloc/free is enabled. With this change, kernel_init_free_pages() is no longer called when both HW_TAGS KASAN and init_on_alloc/free are enabled. Instead, memory is initialized in KASAN runtime. To avoid discrepancies with which memory gets initialized that can be caused by future changes, both KASAN and kernel_init_free_pages() hooks are put together and a warning comment is added. This patch changes the order in which memory initialization and page poisoning hooks are called. This doesn't lead to any side-effects, as whenever page poisoning is enabled, memory initialization gets disabled. Combining setting allocation tags with memory initialization improves HW_TAGS KASAN performance when init_on_alloc/free is enabled.

FROMGIT: mm: introduce debug_pagealloc_{map,unmap}_pages() helpers
Patch series "arch, mm: improve robustness of direct map manipulation", v7. During recent discussion about KVM protected memory, David raised a concern about usage of __kernel_map_pages() outside of DEBUG_PAGEALLOC scope [1]. Indeed, for architectures that define CONFIG_ARCH_HAS_SET_DIRECT_MAP it is possible that __kernel_map_pages() would fail, but since this function is void, the failure will go unnoticed. Moreover, there's lack of consistency of __kernel_map_pages() semantics across architectures as some guard this function with #ifdef DEBUG_PAGEALLOC, some refuse to update the direct map if page allocation debugging is disabled at run time and some allow modifying the direct map regardless of DEBUG_PAGEALLOC settings. This set straightens this out by restoring dependency of __kernel_map_pages() on DEBUG_PAGEALLOC and updating the call sites accordingly. Since currently the only user of __kernel_map_pages() outside DEBUG_PAGEALLOC is hibernation, it is updated to make direct map accesses there more explicit. [1] https://lore.kernel.org/lkml/2759b4bf-e1e3-d006-7d86-78a40348269d@redhat.com This patch (of 4): When CONFIG_DEBUG_PAGEALLOC is enabled, it unmaps pages from the kernel direct mapping after free_pages(). The pages than need to be mapped back before they could be used. Theese mapping operations use __kernel_map_pages() guarded with with debug_pagealloc_enabled(). The only place that calls __kernel_map_pages() without checking whether DEBUG_PAGEALLOC is enabled is the hibernation code that presumes availability of this function when ARCH_HAS_SET_DIRECT_MAP is set. Still, on arm64, __kernel_map_pages() will bail out when DEBUG_PAGEALLOC is not enabled but set_direct_map_invalid_noflush() may render some pages not present in the direct map and hibernation code won't be able to save such pages. To make page allocation debugging and hibernation interaction more robust, the dependency on DEBUG_PAGEALLOC or ARCH_HAS_SET_DIRECT_MAP has to be made more explicit. Start with combining the guard condition and the call to __kernel_map_pages() into debug_pagealloc_map_pages() and debug_pagealloc_unmap_pages() functions to emphasize that __kernel_map_pages() should not be called without DEBUG_PAGEALLOC and use these new functions to map/unmap pages when page allocation debugging is enabled.

BACKPORT: mm, page_alloc: do not rely on the order of page_poison and init_on_alloc/free parameters
Patch series "cleanup page poisoning", v3. I have identified a number of issues and opportunities for cleanup with CONFIG_PAGE_POISON and friends: - interaction with init_on_alloc and init_on_free parameters depends on the order of parameters (Patch 1) - the boot time enabling uses static key, but inefficienty (Patch 2) - sanity checking is incompatible with hibernation (Patch 3) - CONFIG_PAGE_POISONING_NO_SANITY can be removed now that we have init_on_free (Patch 4) - CONFIG_PAGE_POISONING_ZERO can be most likely removed now that we have init_on_free (Patch 5) This patch (of 5): Enabling page_poison=1 together with init_on_alloc=1 or init_on_free=1 produces a warning in dmesg that page_poison takes precedence. However, as these warnings are printed in early_param handlers for init_on_alloc/free, they are not printed if page_poison is enabled later on the command line (handlers are called in the order of their parameters), or when init_on_alloc/free is always enabled by the respective config option - before the page_poison early param handler is called, it is not considered to be enabled. This is inconsistent. We can remove the dependency on order by making the init_on_* parameters only set a boolean variable, and postponing the evaluation after all early params have been processed. Introduce a new init_mem_debugging_and_hardening() function for that, and move the related debug_pagealloc processing there as well. As a result init_mem_debugging_and_hardening() knows always accurately if init_on_* and/or page_poison options were enabled. Thus we can also optimize want_init_on_alloc() and want_init_on_free(). We don't need to check page_poisoning_enabled() there, we can instead not enable the init_on_* static keys at all, if page poisoning is enabled. This results in a simpler and more effective code.

FROMGIT: mm, kasan: don't poison boot memory with tag-based modes
During boot, all non-reserved memblock memory is exposed to page_alloc via memblock_free_pages->__free_pages_core(). This results in kasan_free_pages() being called, which poisons that memory. Poisoning all that memory lengthens boot time. The most noticeable effect is observed with the HW_TAGS mode. A boot-time impact may potentially also affect systems with large amount of RAM. This patch changes the tag-based modes to not poison the memory during the memblock->page_alloc transition. An exception is made for KASAN_GENERIC. Since it marks all new memory as accessible, not poisoning the memory released from memblock will lead to KASAN missing invalid boot-time accesses to that memory. With KASAN_SW_TAGS, as it uses the invalid 0xFE tag as the default tag for all memory, it won't miss bad boot-time accesses even if the poisoning of memblock memory is removed. With KASAN_HW_TAGS, the default memory tags values are unspecified. Therefore, if memblock poisoning is removed, this KASAN mode will miss the mentioned type of boot-time bugs with a 1/16 probability. This is taken as an acceptable trafe-off. Internally, the poisoning is removed as follows. __free_pages_core() is used when exposing fresh memory during system boot and when onlining memory during hotplug. This patch adds a new FPI_SKIP_KASAN_POISON flag and passes it to __free_pages_ok() through free_pages_prepare() from __free_pages_core(). If FPI_SKIP_KASAN_POISON is set, kasan_free_pages() is not called. All memory allocated normally when the boot is over keeps getting poisoned as usual.

FROMGIT: kasan, mm: fix crash with HW_TAGS and DEBUG_PAGEALLOC
Currently, kasan_free_nondeferred_pages()->kasan_free_pages() is called after debug_pagealloc_unmap_pages(). This causes a crash when debug_pagealloc is enabled, as HW_TAGS KASAN can't set tags on an unmapped page. This patch puts kasan_free_nondeferred_pages() before debug_pagealloc_unmap_pages() and arch_free_page(), which can also make the page unavailable.

FROMLIST: mm: replace migrate_[prep|finish] with lru_cache_[disable|enable]
Currently, migrate_[prep|finish] is merely a wrapper of lru_cache_[disable|enable]. There is not much to gain from having additional abstraction. Use lru_cache_[disable|enable] instead of migrate_[prep|finish], which would be more descriptive. note: migrate_prep_local in compaction.c changed into lru_add_drain to avoid CPU schedule cost with involving many other CPUs to keep keep old behavior.

BACKPORT: FROMLIST: mm: disable LRU pagevec during the migration temporarily
LRU pagevec holds refcount of pages until the pagevec are drained.
It could prevent migration since the refcount of the page is greater
than the expection in migration logic. To mitigate the issue,
callers of migrate_pages drains LRU pagevec via migrate_prep or
lru_add_drain_all before migrate_pages call.
However, it's not enough because pages coming into pagevec after the
draining call still could stay at the pagevec so it could keep
preventing page migration. Since some callers of migrate_pages have
retrial logic with LRU draining, the page would migrate at next trail
but it is still fragile in that it doesn't close the fundamental race
between upcoming LRU pages into pagvec and migration so the migration
failure could cause contiguous memory allocation failure in the end.
To close the race, this patch disables lru caches(i.e, pagevec)
during ongoing migration until migrate is done.
Since it's really hard to reproduce, I measured how many times
migrate_pages retried with force mode(it is about a fallback to a
sync migration) with below debug code.
int migrate_pages(struct list_head *from, new_page_t get_new_page,
..
..
if (rc && reason == MR_CONTIG_RANGE && pass > 2) {
printk(KERN_ERR, "pfn 0x%lx reason %d\n", page_to_pfn(page), rc);
dump_page(page, "fail to migrate");
}
The test was repeating android apps launching with cma allocation
in background every five seconds. Total cma allocation count was
about 500 during the testing. With this patch, the dump_page count
was reduced from 400 to 30.
The new interface is also useful for memory hotplug which currently
drains lru pcp caches after each migration failure. This is rather
suboptimal as it has to disrupt others running during the operation.
With the new interface the operation happens only once. This is also in
line with pcp allocator cache which are disabled for the offlining as
well.

mm/page_alloc.c: refactor initialization of struct page for holes in memory layout
commit 0740a50b9baa4472cfb12442df4b39e2712a64a4 upstream. There could be struct pages that are not backed by actual physical memory. This can happen when the actual memory bank is not a multiple of SECTION_SIZE or when an architecture does not register memory holes reserved by the firmware as memblock.memory. Such pages are currently initialized using init_unavailable_mem() function that iterates through PFNs in holes in memblock.memory and if there is a struct page corresponding to a PFN, the fields of this page are set to default values and it is marked as Reserved. init_unavailable_mem() does not take into account zone and node the page belongs to and sets both zone and node links in struct page to zero.

FROMLIST: mm: replace migrate_prep with lru_add_drain_all
Currently, migrate_prep is merely a wrapper of lru_cache_add_all. There is not much to gain from having additional abstraction. Use lru_add_drain_all instead of migrate_prep, which would be more descriptive. note: migrate_prep_local in compaction.c changed into lru_add_drain to avoid CPU schedule cost with involving many other CPUs to keep keep old behavior.

FROMLIST: mm: page_alloc: dump migrate-failed pages
Currently, debugging CMA allocation failures is quite limited. The most common source of these failures seems to be page migration which doesn't provide any useful information on the reason of the failure by itself. alloc_contig_range can report those failures as it holds a list of migrate-failed pages. The information logged by dump_page() has already proven helpful for debugging allocation issues, like identifying long-term pinnings on ZONE_MOVABLE or MIGRATE_CMA. Let's use the dynamic debugging infrastructure, such that we avoid flooding the logs and creating a lot of noise on frequent alloc_contig_range() calls. This information is helpful for debugging only. There are two ifdefery conditions to support common dyndbg options: - CONFIG_DYNAMIC_DEBUG_CORE && DYNAMIC_DEBUG_MODULE It aims for supporting the feature with only specific file with adding ccflags. - CONFIG_DYNAMIC_DEBUG It aims for supporting the feature with system wide globally. A simple example to enable the feature: Admin could enable the dump like this(by default, disabled) echo "func alloc_contig_dump_pages +p" > control Admin could disable it. echo "func alloc_contig_dump_pages =_" > control Detail goes Documentation/admin-guide/dynamic-debug-howto.rst A concern is utility functions in dump_page use inconsistent loglevels. In the future, we might want to make the loglevels used inside dump_page() consistent and eventually rework the way we log the information here. See [1].

FROMGIT: mm: remove lru_add_drain_all in alloc_contig_range
__alloc_contig_migrate_range already has lru_add_drain_all call via
migrate_prep. It's necessary to move LRU taget pages into LRU list to be
able to isolated. However, lru_add_drain_all call after
__alloc_contig_migrate_range is pointless since it has changed source page
freeing from putback_lru_pages to put_page[1].
This patch removes it.
