We currently plan to disallow use of filp_open() from drivers in GKI,
however the ZRAM driver still needs it. Add a new GKI-only variant of
filp_open() which only permits a block device to be opened, which can
be exported instead. This keeps ZRAM working but cuts down on drivers
that attempt to open and write files in kernel mode.

Now that generic_set_encrypted_ci_d_ops() has been added and ext4 and
f2fs are using it, it's no longer necessary to export
generic_ci_d_compare() and generic_ci_d_hash() to filesystems.

OverlayFS implements its own function to translate iocb flags into rw
flags, so that they can be passed into another vfs call.
With commit ce71bfea20 ("fs: align IOCB_* flags with RWF_* flags")
Jens created a 1:1 matching between the iocb flags and rw flags,
simplifying the conversion.
Reduce the OverlayFS code by making the flag conversion function generic
and reusable.

[ Upstream commit 88149082bb8ef31b289673669e080ec6a00c2e59 ]
If generic_drop_inode() returns true, it means iput_final() can evict
this inode regardless of whether it is dirty or not. If we check
I_DONTCACHE in generic_drop_inode(), any inode with this bit set will be
evicted unconditionally. This is not the desired behavior because
I_DONTCACHE only means the inode shouldn't be cached on the LRU list.
As for whether we need to evict this inode, this is what
generic_drop_inode() should do. This patch corrects the usage of
I_DONTCACHE.
This patch was proposed in [1].

This adds a function to set dentry operations at lookup time that will
work for both encrypted filenames and casefolded filenames.
A filesystem that supports both features simultaneously can use this
function during lookup preparations to set up its dentry operations once
fscrypt no longer does that itself.
Currently the casefolding dentry operation are always set if the
filesystem defines an encoding because the features is toggleable on
empty directories. Unlike in the encryption case, the dentry operations
used come from the parent. Since we don't know what set of functions
we'll eventually need, and cannot change them later, we enable the
casefolding operations if the filesystem supports them at all.
By splitting out the various cases, we support as few dentry operations
as we can get away with, maximizing compatibility with overlayfs, which
will not function if a filesystem supports certain dentry_operations.

Pull fs freeze fix and cleanups from Darrick Wong:
"A single vfs fix for 5.10, along with two subsequent cleanups.
A very long time ago, a hack was added to the vfs fs freeze protection
code to work around lockdep complaints about XFS, which would try to
run a transaction (which requires intwrite protection) to finalize an
xfs freeze (by which time the vfs had already taken intwrite).
Fast forward a few years, and XFS fixed the recursive intwrite problem
on its own, and the hack became unnecessary. Fast forward almost a
decade, and latent bugs in the code converting this hack from freeze
flags to freeze locks combine with lockdep bugs to make this reproduce
frequently enough to notice page faults racing with freeze.
Since the hack is unnecessary and causes thread race errors, just get
rid of it completely. Making this kind of vfs change midway through a
cycle makes me nervous, but a large enough number of the usual
VFS/ext4/XFS/btrfs suspects have said this looks good and solves a
real problem vector.
And once that removal is done, __sb_start_write is now simple enough
that it becomes possible to refactor the function into smaller,
simpler static inline helpers in linux/fs.h. The cleanup is
straightforward.
Summary:
- Finally remove the "convert to trylock" weirdness in the fs freezer
code. It was necessary 10 years ago to deal with nested
transactions in XFS, but we've long since removed that; and now
this is causing subtle race conditions when lockdep goes offline
and sb_start_* aren't prepared to retry a trylock failure.
- Minor cleanups of the sb_start_* fs freeze helpers"
* tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
vfs: move __sb_{start,end}_write* to fs.h
vfs: separate __sb_start_write into blocking and non-blocking helpers
vfs: remove lockdep bogosity in __sb_start_write
Now that we've straightened out the callers, move these three functions
to fs.h since they're fairly trivial.

Break this function into two helpers so that it's obvious that the
trylock versions return a value that must be checked, and the blocking
versions don't require that. While we're at it, clean up the return
type mismatch.

Enhancements:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping method
Bug fixes:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image

Complete the migration by moving the file remapping helper functions out
of read_write.c and into remap_range.c. This reduces the clutter in the
first file and (eventually) will make it so that we can compile out the
second file if it isn't needed.

I would like to move all the generic helpers for the vfs remap range
functionality (aka clonerange and dedupe) into a separate file so that
they won't be scattered across the vfs and the mm subsystems. The
eventual goal is to be able to deselect remap_range.c if none of the
filesystems need that code, but the tricky part here is picking a
stable(ish) part of the merge window to rearrange code.

Our users reported that there're some random latency spikes when their RT
process is running. Finally we found that latency spike is caused by
FADV_DONTNEED. Which may call lru_add_drain_all() to drain LRU cache on
remote CPUs, and then waits the per-cpu work to complete. The wait time
is uncertain, which may be tens millisecond.
That behavior is unreasonable, because this process is bound to a specific
CPU and the file is only accessed by itself, IOW, there should be no
pagecache pages on a per-cpu pagevec of a remote CPU. That unreasonable
behavior is partially caused by the wrong comparation of the number of
invalidated pages and the number of the target. For example,
if (count < (end_index - start_index + 1))
The count above is how many pages were invalidated in the local CPU, and
(end_index - start_index + 1) is how many pages should be invalidated.
The usage of (end_index - start_index + 1) is incorrect, because they are
virtual addresses, which may not mapped to pages. Besides that, there may
be holes between start and end. So we'd better check whether there are
still pages on per-cpu pagevec after drain the local cpu, and then decide
whether or not to call lru_add_drain_all().
After I applied it with a hotfix to our production environment, most of
the lru_add_drain_all() can be avoided.

Pull btrfs updates from David Sterba:
"Mostly core updates with a few user visible bits and fixes.
Hilights:
- fsync performance improvements
- less contention of log mutex (throughput +4%, latency -14%,
dbench with 32 clients)
- skip unnecessary commits for link and rename (throughput +6%,
latency -30%, rename latency -75%, dbench with 16 clients)
- make fast fsync wait only for writeback (throughput +10..40%,
runtime -1..-20%, dbench with 1 to 64 clients on various
file/block sizes)
- direct io is now implemented using the iomap infrastructure, that's
the main part, we still have a workaround that requires an iomap
API update, coming in 5.10
- new sysfs exports:
- information about the exclusive filesystem operation status
(balance, device add/remove/replace, ...)
- supported send stream version
Core:
- use ticket space reservations for data, fair policy using the same
infrastructure as metadata
- preparatory work to switch locking from our custom tree locks to
standard rwsem, now the locking context is propagated to all
callers, actual switch is expected to happen in the next dev cycle
- seed device structures are now using list API
- extent tracepoints print proper tree id
- unified range checks for extent buffer helpers
- send: avoid using temporary buffer for copying data
- remove unnecessary RCU protection from space infos
- remove unused readpage callback for metadata, enabling several
cleanups
- replace indirect function calls for end io hooks and remove
extent_io_ops completely
Fixes:
- more lockdep warning fixes
- fix qgroup reservation for delayed inode and an occasional
reservation leak for preallocated files
- fix device replace of a seed device
- fix metadata reservation for fallocate that leads to transaction
aborts
- reschedule if necessary when logging directory items or when
cloning lots of extents
- tree-checker: fix false alert caused by legacy btrfs root item
- send: fix rename/link conflicts for orphanized inodes
- properly initialize device stats for seed devices
- skip devices without magic signature when mounting
Other:
- error handling improvements, BUG_ONs replaced by proper handling,
fuzz fixes
- various function parameter cleanups
- various W=1 cleanups
- error/info messages improved
Mishaps:
- commit 62cf539120 ("btrfs: move btrfs_rm_dev_replace_free_srcdev

merged to 5.9-rc8 as a466c85edc ("btrfs: move

Split rw_copy_check_uvector into two new helpers with more sensible
calling conventions:
- iovec_from_user copies a iovec from userspace either into the provided
stack buffer if it fits, or allocates a new buffer for it. Returns
the actually used iovec. It also verifies that iov_len does fit a
signed type, and handles compat iovecs if the compat flag is set.
- __import_iovec consolidates the native and compat versions of
import_iovec. It calls iovec_from_user, then validates each iovec
actually points to user addresses, and ensures the total length
doesn't overflow.
This has two major implications:
- the access_process_vm case loses the total lenght checking, which
wasn't required anyway, given that each call receives two iovecs
for the local and remote side of the operation, and it verifies
the total length on the local side already.
- instead of a single loop there now are two loops over the iovecs.
Given that the iovecs are cache hot this doesn't make a major
difference
