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.

UPSTREAM: mm/page_alloc: count CMA pages per zone and print them in /proc/zoneinfo
Let's count the number of CMA pages per zone and print them in /proc/zoneinfo. Having access to the total number of CMA pages per zone is helpful for debugging purposes to know where exactly the CMA pages ended up, and to figure out how many pages of a zone might behave differently, even after some of these pages might already have been allocated. As one example, CMA pages part of a kernel zone cannot be used for ordinary kernel allocations but instead behave more like ZONE_MOVABLE. For now, we are only able to get the global nr+free cma pages from /proc/meminfo and the free cma pages per zone from /proc/zoneinfo. Example after this patch when booting a 6 GiB QEMU VM with "hugetlb_cma=2G": # cat /proc/zoneinfo | grep cma cma 0 nr_free_cma 0 cma 0 nr_free_cma 0 cma 524288 nr_free_cma 493016 cma 0 cma 0 # cat /proc/meminfo | grep Cma CmaTotal: 2097152 kB CmaFree: 1972064 kB Note: We print even without CONFIG_CMA, just like "nr_free_cma"; this way, one can be sure when spotting "cma 0", that there are definetly no CMA pages located in a zone.

UPSTREAM: kasan, mm: fix resetting page_alloc tags for HW_TAGS
[ Upstream commit acb35b177c71d3d39b9a3b9ea213d926235066e3 ] A previous commit added resetting KASAN page tags to kernel_init_free_pages() to avoid false-positives due to accesses to metadata with the hardware tag-based mode.

mm: fix initialization of struct page for holes in memory layout
commit d3921cb8be29ce5668c64e23ffdaeec5f8c69399 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 if this page
are set to default values and the page 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.
On a system that has firmware reserved holes in a zone above ZONE_DMA,
for instance in a configuration below:
# grep -A1 E820 /proc/iomem
7a17b000-7a216fff : Unknown E820 type
7a217000-7bffffff : System RAM
unset zone link in struct page will trigger
VM_BUG_ON_PAGE(!zone_spans_pfn(page_zone(page), pfn), page);
because there are pages in both ZONE_DMA32 and ZONE_DMA (unset zone link
in struct page) in the same pageblock.
Update init_unavailable_mem() to use zone constraints defined by an
architecture to properly setup the zone link and use node ID of the
adjacent range in memblock.memory to set the node link.

FROMLIST: mm: failfast mode with __GFP_NORETRY in alloc_contig_range
Contiguous memory allocation can be stalled due to waiting on page writeback and/or page lock which causes unpredictable delay. It's a unavoidable cost for the requestor to get *big* contiguous memory but it's expensive for *small* contiguous memory(e.g., order-4) because caller could retry the request in different range where would have easy migratable pages without stalling. This patch introduce __GFP_NORETRY as compaction gfp_mask in alloc_contig_range so it will fail fast without blocking when it encounters pages needed waiting.

ANDROID: mm: use alloc_flags for cma first alloc policy
rmqueue internal functions to allocate cma memory should use alloc_flags instead of gfp_flags because it's more restricted flags to be considered allocation context. Otherwise, we could allocate page from CMA area even though current context already disable cma memory allocation. For example, current allocation context is limited not to allocate the page from CMA area by PF_MEMALLOC_NOCMA to prevent longterm pin but it's ignored so the longterm pin page could be allocated from CMA area.

UPSTREAM: kasan, mm: reset tags when accessing metadata
[ Upstream commit aa1ef4d7b3f67f7f17aa4aa34f5ec513c7e4db6c ] Kernel allocator code accesses metadata for slab objects, that may lie out-of-bounds of the object itself, or be accessed when an object is freed. Such accesses trigger tag faults and lead to false-positive reports with hardware tag-based KASAN. Software KASAN modes disable instrumentation for allocator code via KASAN_SANITIZE Makefile macro, and rely on kasan_enable/disable_current() annotations which are used to ignore KASAN reports. With hardware tag-based KASAN neither of those options are available, as it doesn't use compiler instrumetation, no tag faults are ignored, and MTE is disabled after the first one. Instead, reset tags when accessing metadata (currently only for SLUB).

mm: don't wake kswapd prematurely when watermark boosting is disabled
[ Upstream commit 597c892038e08098b17ccfe65afd9677e6979800 ]
On 2-node NUMA hosts we see bursts of kswapd reclaim and subsequent
pressure spikes and stalls from cache refaults while there is plenty of
free memory in the system.
Usually, kswapd is woken up when all eligible nodes in an allocation are
full. But the code related to watermark boosting can wake kswapd on one
full node while the other one is mostly empty. This may be justified to
fight fragmentation, but is currently unconditionally done whether
watermark boosting is occurring or not.
In our case, many of our workloads' throughput scales with available
memory, and pure utilization is a more tangible concern than trends
around longer-term fragmentation. As a result we generally disable
watermark boosting.
Wake kswapd only woken when watermark boosting is requested.

ANDROID: cma: redirect page allocation to CMA
CMA pages are designed to be used as fallback for movable allocations and cannot be used for non-movable allocations. If CMA pages are utilized poorly, non-movable allocations may end up getting starved if all regular movable pages are allocated and the only pages left are CMA. Always using CMA pages first creates unacceptable performance problems. As a midway alternative, use CMA pages for certain userspace allocations. The userspace pages can be migrated or dropped quickly which giving decent utilization. Additionally, add a fall-backs for failed CMA allocations in rmqueue() and __rmqueue_pcplist() (the latter addition being driven by a report by the kernel test robot); these fallbacks were dealt with differently in the original version of the patch as the rmqueue() call chain has changed).

page_frag: Recover from memory pressure
The ethernet driver may allocate skb (and skb->data) via napi_alloc_skb().
This ends up to page_frag_alloc() to allocate skb->data from
page_frag_cache->va.
During the memory pressure, page_frag_cache->va may be allocated as
pfmemalloc page. As a result, the skb->pfmemalloc is always true as
skb->data is from page_frag_cache->va. The skb will be dropped if the
sock (receiver) does not have SOCK_MEMALLOC. This is expected behaviour
under memory pressure.
However, once kernel is not under memory pressure any longer (suppose large
amount of memory pages are just reclaimed), the page_frag_alloc() may still
re-use the prior pfmemalloc page_frag_cache->va to allocate skb->data. As a
result, the skb->pfmemalloc is always true unless page_frag_cache->va is
re-allocated, even if the kernel is not under memory pressure any longer.
Here is how kernel runs into issue.
1. The kernel is under memory pressure and allocation of
PAGE_FRAG_CACHE_MAX_ORDER in __page_frag_cache_refill() will fail. Instead,
the pfmemalloc page is allocated for page_frag_cache->va.
2: All skb->data from page_frag_cache->va (pfmemalloc) will have
skb->pfmemalloc=true. The skb will always be dropped by sock without
SOCK_MEMALLOC. This is an expected behaviour.
3. Suppose a large amount of pages are reclaimed and kernel is not under
memory pressure any longer. We expect skb->pfmemalloc drop will not happen.
4. Unfortunately, page_frag_alloc() does not proactively re-allocate
page_frag_alloc->va and will always re-use the prior pfmemalloc page. The
skb->pfmemalloc is always true even kernel is not under memory pressure any
longer.
Fix this by freeing and re-allocating the page instead of recycling it.

mm/page_alloc: place pages to tail in __free_pages_core()
__free_pages_core() is used when exposing fresh memory to the buddy during system boot and when onlining memory in generic_online_page(). generic_online_page() is used in two cases: 1. Direct memory onlining in online_pages(). 2. Deferred memory onlining in memory-ballooning-like mechanisms (HyperV balloon and virtio-mem), when parts of a section are kept fake-offline to be fake-onlined later on. In 1, we already place pages to the tail of the freelist. Pages will be freed to MIGRATE_ISOLATE lists first and moved to the tail of the freelists via undo_isolate_page_range(). In 2, we currently don't implement a proper rule. In case of virtio-mem, where we currently always online MAX_ORDER - 1 pages, the pages will be placed to the HEAD of the freelist - undesireable. While the hyper-v balloon calls generic_online_page() with single pages, usually it will call it on successive single pages in a larger block. The pages are fresh, so place them to the tail of the freelist and avoid the PCP. In __free_pages_core(), remove the now superflouos call to set_page_refcounted() and add a comment regarding page initialization and the refcount. Note: In 2. we currently don't shuffle. If ever relevant (page shuffling is usually of limited use in virtualized environments), we might want to shuffle after a sequence of generic_online_page() calls in the relevant callers.

mm/page_alloc: move pages to tail in move_to_free_list()
Whenever we move pages between freelists via move_to_free_list()/ move_freepages_block(), we don't actually touch the pages: 1. Page isolation doesn't actually touch the pages, it simply isolates pageblocks and moves all free pages to the MIGRATE_ISOLATE freelist. When undoing isolation, we move the pages back to the target list. 2. Page stealing (steal_suitable_fallback()) moves free pages directly between lists without touching them. 3. reserve_highatomic_pageblock()/unreserve_highatomic_pageblock() moves free pages directly between freelists without touching them. We already place pages to the tail of the freelists when undoing isolation via __putback_isolated_page(), let's do it in any case (e.g., if order <= pageblock_order) and document the behavior. To simplify, let's move the pages to the tail for all move_to_free_list()/move_freepages_block() users. In 2., the target list is empty, so there should be no change. In 3., we might observe a change, however, highatomic is more concerned about allocations succeeding than cache hotness - if we ever realize this change degrades a workload, we can special-case this instance and add a proper comment. This change results in all pages getting onlined via online_pages() to be placed to the tail of the freelist.

mm/page_alloc: place pages to tail in __putback_isolated_page()
__putback_isolated_page() already documents that pages will be placed to the tail of the freelist - this is, however, not the case for "order >= MAX_ORDER - 2" (see buddy_merge_likely()) - which should be the case for all existing users. This change affects two users: - free page reporting - page isolation, when undoing the isolation (including memory onlining). This behavior is desirable for pages that haven't really been touched lately, so exactly the two users that don't actually read/write page content, but rather move untouched pages. The new behavior is especially desirable for memory onlining, where we allow allocation of newly onlined pages via undo_isolate_page_range() in online_pages(). Right now, we always place them to the head of the freelist, resulting in undesireable behavior: Assume we add individual memory chunks via add_memory() and online them right away to the NORMAL zone. We create a dependency chain of unmovable allocations e.g., via the memmap. The memmap of the next chunk will be placed onto previous chunks - if the last block cannot get offlined+removed, all dependent ones cannot get offlined+removed. While this can already be observed with individual DIMMs, it's more of an issue for virtio-mem (and I suspect also ppc DLPAR). Document that this should only be used for optimizations, and no code should rely on this behavior for correction (if the order of the freelists ever changes). We won't care about page shuffling: memory onlining already properly shuffles after onlining. free page reporting doesn't care about physically contiguous ranges, and there are already cases where page isolation will simply move (physically close) free pages to (currently) the head of the freelists via move_freepages_block() instead of shuffling. If this becomes ever relevant, we should shuffle the whole zone when undoing isolation of larger ranges, and after free_contig_range().
