Pull fscache rewrite from David Howells:
"This is a set of patches that rewrites the fscache driver and the
cachefiles driver, significantly simplifying the code compared to
what's upstream, removing the complex operation scheduling and object
state machine in favour of something much smaller and simpler.
The series is structured such that the first few patches disable
fscache use by the network filesystems using it, remove the cachefiles
driver entirely and as much of the fscache driver as can be got away
with without causing build failures in the network filesystems.
The patches after that recreate fscache and then cachefiles,
attempting to add the pieces in a logical order. Finally, the
filesystems are reenabled and then the very last patch changes the
documentation.
[!] Note: I have dropped the cifs patch for the moment, leaving local
caching in cifs disabled. I've been having trouble getting that
working. I think I have it done, but it needs more testing (there
seem to be some test failures occurring with v5.16 also from
xfstests), so I propose deferring that patch to the end of the
merge window.
WHY REWRITE?
============
Fscache's operation scheduling API was intended to handle sequencing
of cache operations, which were all required (where possible) to run
asynchronously in parallel with the operations being done by the
network filesystem, whilst allowing the cache to be brought online and
offline and to interrupt service for invalidation.
With the advent of the tmpfile capacity in the VFS, however, an
opportunity arises to do invalidation much more simply, without having
to wait for I/O that's actually in progress: Cachefiles can simply
create a tmpfile, cut over the file pointer for the backing object
attached to a cookie and abandon the in-progress I/O, dismissing it
upon completion.
Future work here would involve using Omar Sandoval's vfs_link() with
AT_LINK_REPLACE[1] to allow an extant file to be displaced by a new
hard link from a tmpfile as currently I have to unlink the old file
first.
These patches can also simplify the object state handling as I/O
operations to the cache don't all have to be brought to a stop in
order to invalidate a file. To that end, and with an eye on to writing
a new backing cache model in the future, I've taken the opportunity to
simplify the indexing structure.
I've separated the index cookie concept from the file cookie concept
by C type now. The former is now called a "volume cookie" (struct
fscache_volume) and there is a container of file cookies. There are
then just the two levels. All the index cookie levels are collapsed
into a single volume cookie, and this has a single printable string as
a key. For instance, an AFS volume would have a key of something like
"afs,example.com,1000555", combining the filesystem name, cell name
and volume ID. This is freeform, but must not have '/' chars in it.
I've also eliminated all pointers back from fscache into the network
filesystem. This required the duplication of a little bit of data in
the cookie (cookie key, coherency data and file size), but it's not
actually that much. This gets rid of problems with making sure we keep
netfs data structures around so that the cache can access them.
These patches mean that most of the code that was in the drivers
before is simply gone and those drivers are now almost entirely new
code. That being the case, there doesn't seem any particular reason to
try and maintain bisectability across it. Further, there has to be a
point in the middle where things are cut over as there's a single
point everything has to go through (ie. /dev/cachefiles) and it can't
be in use by two drivers at once.
ISSUES YET OUTSTANDING
======================
There are some issues still outstanding, unaddressed by this patchset,
that will need fixing in future patchsets, but that don't stop this
series from being usable:
(1) The cachefiles driver needs to stop using the backing filesystem's
metadata to store information about what parts of the cache are
populated. This is not reliable with modern extent-based
filesystems.
Fixing this is deferred to a separate patchset as it involves
negotiation with the network filesystem and the VM as to how much
data to download to fulfil a read - which brings me on to (2)...
(2) NFS (and CIFS with the dropped patch) do not take account of how
the cache would like I/O to be structured to meet its granularity
requirements. Previously, the cache used page granularity, which
was fine as the network filesystems also dealt in page
granularity, and the backing filesystem (ext4, xfs or whatever)
did whatever it did out of sight. However, we now have folios to
deal with and the cache will now have to store its own metadata to
track its contents.
The change I'm looking at making for cachefiles is to store
content bitmaps in one or more xattrs and making a bit in the map
correspond to something like a 256KiB block. However, the size of
an xattr and the fact that they have to be read/updated in one go
means that I'm looking at covering 1GiB of data per 512-byte map
and storing each map in an xattr. Cachefiles has the potential to
grow into a fully fledged filesystem of its very own if I'm not
careful.
However, I'm also looking at changing things even more radically
and going to a different model of how the cache is arranged and
managed - one that's more akin to the way, say, openafs does
things - which brings me on to (3)...
(3) The way cachefilesd does culling is very inefficient for large
caches and it would be better to move it into the kernel if I can
as cachefilesd has to keep asking the kernel if it can cull a
file. Changing the way the backend works would allow this to be
addressed.
BITS THAT MAY BE CONTROVERSIAL
==============================
There are some bits I've added that may be controversial:
(1) I've provided a flag, S_KERNEL_FILE, that cachefiles uses to check
if a files is already being used by some other kernel service
(e.g. a duplicate cachefiles cache in the same directory) and
reject it if it is. This isn't entirely necessary, but it helps
prevent accidental data corruption.
I don't want to use S_SWAPFILE as that has other effects, but
quite possibly swapon() should set S_KERNEL_FILE too.
Note that it doesn't prevent userspace from interfering, though
perhaps it should. (I have made it prevent a marked directory from
being rmdir-able).
(2) Cachefiles wants to keep the backing file for a cookie open whilst
we might need to write to it from network filesystem writeback.
The problem is that the network filesystem unuses its cookie when
its file is closed, and so we have nothing pinning the cachefiles
file open and it will get closed automatically after a short time
to avoid EMFILE/ENFILE problems.
Reopening the cache file, however, is a problem if this is being
done due to writeback triggered by exit(). Some filesystems will
oops if we try to open a file in that context because they want to
access current->fs or suchlike.
To get around this, I added the following:
(A) An inode flag, I_PINNING_FSCACHE_WB, to be set on a network
filesystem inode to indicate that we have a usage count on the
cookie caching that inode.
(B) A flag in struct writeback_control, unpinned_fscache_wb, that
is set when __writeback_single_inode() clears the last dirty
page from i_pages - at which point it clears
I_PINNING_FSCACHE_WB and sets this flag.
This has to be done here so that clearing I_PINNING_FSCACHE_WB
can be done atomically with the check of PAGECACHE_TAG_DIRTY
that clears I_DIRTY_PAGES.
(C) A function, fscache_set_page_dirty(), which if it is not set,
sets I_PINNING_FSCACHE_WB and calls fscache_use_cookie() to
pin the cache resources.
(D) A function, fscache_unpin_writeback(), to be called by
->write_inode() to unuse the cookie.
(E) A function, fscache_clear_inode_writeback(), to be called when
the inode is evicted, before clear_inode() is called. This
cleans up any lingering I_PINNING_FSCACHE_WB.
The network filesystem can then use these tools to make sure that
fscache_write_to_cache() can write locally modified data to the
cache as well as to the server.
For the future, I'm working on write helpers for netfs lib that
should allow this facility to be removed by keeping track of the
dirty regions separately - but that's incomplete at the moment and
is also going to be affected by folios, one way or another, since
it deals with pages"

Pull xfs updates from Darrick Wong:
"The big new feature here is that the mount code now only bothers to
try to free stale COW staging extents if the fs unmounted uncleanly.
This should reduce mount times, particularly on filesystems supporting
reflink and containing a large number of allocation groups.
Everything else this cycle are bugfixes, as the iomap folios
conversion should be plenty enough excitement for anyone. That and I
ran out of brain bandwidth after Thanksgiving last year.
Summary:
- Fix log recovery with da btree buffers when metauuid is in use.
- Fix type coercion problems in xattr buffer size validation.
- Fix a bug in online scrub dir leaf bestcount checking.
- Only run COW recovery when recovering the log.
- Fix symlink target buffer UAF problems and symlink locking problems
by not exposing xfs innards to the VFS.
- Fix incorrect quotaoff lock usage.
- Don't let transactions cancel cleanly if they have deferred work
items attached.
- Fix a UAF when we're deciding if we need to relog an intent item.
- Reduce kvmalloc overhead for log shadow buffers.
- Clean up sysfs attr group usage.
- Fix a bug where scrub's bmap/rmap checking could race with a quota
file block allocation due to insufficient locking.
- Teach scrub to complain about invalid project ids"

Pull btrfs updates from David Sterba:
"This end of the year branch is intentionally not that exciting. Most
of the changes are under the hood, but there are some minor user
visible improvements and several performance improvements too.
Features:
- make send work with concurrent block group relocation.
We're not allowed to prevent send failing or silently producing
some bad stream but with more fine grained locking and checks it's
possible. The send vs deduplication exclusion could reuse the same
logic in the future.
- new exclusive operation 'balance paused' to allow adding a device
to filesystem with paused balance
- new sysfs file for fsid stored in the per-device directory to help
distinguish devices when seeding is enabled, the fsid may differ
from the one reported by the filesystem
Performance improvements:
- less metadata needed for directory logging, directory deletion is
20-40% faster
- in zoned mode, cache zone information during mount to speed up
repeated queries (about 50% speedup)
- free space tree entries get indexed and searched by size (latency
-30%, search run time -30%)
- less contention in tree node locking when inserting a key and no
splits are needed (files/sec in fsmark improves by 1-20%)
Fixes:
- fix ENOSPC failure when attempting direct IO write into NOCOW range
- fix deadlock between quota enable and other quota operations
- global reserve minimum calculations fixed to account for free space
tree
- in zoned mode, fix condition for chunk allocation that may not find
the right zone for reuse and could lead to early ENOSPC
Core:
- global reserve stealing got simplified and cleaned up in evict
- remove async transaction commit based on manual transaction refs,
reuse existing kthread and mechanisms to let it commit transaction
before timeout
- preparatory work for extent tree v2, add wrappers for global tree
roots, truncation path cleanups
- remove readahead framework, it's a bit overengineered and used only
for scrub, and yet it does not cover all its needs, there is
another readahead built in the b-tree search that is now used,
performance drop on HDD is about 5% which is acceptable and scrub
is often throttled anyway, on SSDs there's no reported drop but
slight improvement
- self tests report extent tree state when error occurs
- replace assert with debugging information when an uncommitted
transaction is found at unmount time
Other:
- error handling improvements
- other cleanups and refactoring"

gfpflags_allow_blocking()
In 9p, afs ceph, and nfs, gfpflags_allow_blocking() (which wraps a
test for __GFP_DIRECT_RECLAIM being set) is used to determine if
->releasepage() should wait for the completion of a DIO write to fscache
with something like:
if (folio_test_fscache(folio)) {
if (!gfpflags_allow_blocking(gfp) || !(gfp & __GFP_FS))
return false;
folio_wait_fscache(folio);
}
Instead, current_is_kswapd() should be used instead.
Note that this is based on a patch originally by Zhaoyang Huang[1]. In
addition to extending it to the other network filesystems and putting it on
top of my fscache rewrite, it also needs to include linux/swap.h in a bunch
of places. Can current_is_kswapd() be moved to linux/mm.h?

Pull fs idmapping updates from Christian Brauner:
"This contains the work to enable the idmapping infrastructure to
support idmapped mounts of filesystems mounted with an idmapping.
In addition this contains various cleanups that avoid repeated
open-coding of the same functionality and simplify the code in quite a
few places.
We also finish the renaming of the mapping helpers we started a few
kernel releases back and move them to a dedicated header to not
continue polluting the fs header needlessly with low-level idmapping
helpers. With this series the fs header only contains idmapping
helpers that interact with fs objects.
Currently we only support idmapped mounts for filesystems mounted
without an idmapping themselves. This was a conscious decision
mentioned in multiple places (cf. [1]).
As explained at length in [3] it is perfectly fine to extend support
for idmapped mounts to filesystem's mounted with an idmapping should
the need arise. The need has been there for some time now (cf. [2]).
Before we can port any filesystem that is mountable with an idmapping
to support idmapped mounts in the coming cycles, we need to first
extend the mapping helpers to account for the filesystem's idmapping.
This again, is explained at length in our documentation at [3] and
also in the individual commit messages so here's an overview.
Currently, the low-level mapping helpers implement the remapping
algorithms described in [3] in a simplified manner as we could rely on
the fact that all filesystems supporting idmapped mounts are mounted
without an idmapping.
In contrast, filesystems mounted with an idmapping are very likely to
not use an identity mapping and will instead use a non-identity
mapping. So the translation step from or into the filesystem's
idmapping in the remapping algorithm cannot be skipped for such
filesystems.
Non-idmapped filesystems and filesystems not supporting idmapped
mounts are unaffected by this change as the remapping algorithms can
take the same shortcut as before. If the low-level helpers detect that
they are dealing with an idmapped mount but the underlying filesystem
is mounted without an idmapping we can rely on the previous shortcut
and can continue to skip the translation step from or into the
filesystem's idmapping. And of course, if the low-level helpers detect
that they are not dealing with an idmapped mount they can simply
return the relevant id unchanged; no remapping needs to be performed
at all.
These checks guarantee that only the minimal amount of work is
performed. As before, if idmapped mounts aren't used the low-level
helpers are idempotent and no work is performed at all"

Now that the fscache API has been reworked and simplified, change ceph
over to use it.
With the old API, we would only instantiate a cookie when the file was
open for reads. Change it to instantiate the cookie when the inode is
instantiated and call use/unuse when the file is opened/closed.
Also, ensure we resize the cached data on truncates, and invalidate the
cache in response to the appropriate events. This will allow us to
plumb in write support later.

- add support for AMDIF031 HID device to gpio-amdpt
- drop support for unused platforms in gpio-xlp
- cleanup leftovers from the removal of the legacy Samsung Exynos

- code shrink in gpiod_add_lookup_table()
- add new model to the DT bindings for gpio-vf610
- convert DT bindings for tegra devices to YAML

Pull spi updates from Mark Brown:
"This has mostly been a quiet release for the SPI subsystem, almost all
cleanups and fixes to existing drivers.
A couple of changes that stand out:
- Cleanups and support for version specific features in the
DesignWare controller.
- Removal of support for Netlogic devices from the XLP driver, the
platform had previously been removed by MIPS so the support
couldn't be used.
- Conversion of several DT bindings to YAML format"
