Merge tag 'for-6.15-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"User visible changes:

- fall back to buffered write if direct io is done on a file that
requires checksums
- this avoids a problem with checksum mismatch errors, observed
e.g. on virtual images when writes to pages under writeback
cause the checksum mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file
attribute that also disables checksums

- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for
sample measurements

- defrag ioctl extended to accept negative compression levels

- subpage mode
- remove warning when subpage mode is used, the feature is now
reasonably complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing
subpage on x86_64 with 4K pages too

Performance improvements:

- in send, better file path caching improves runtime (on sample load
by -30%)

- on s390x with hardware zlib support prepare the input buffer in a
better way to get the best results from the acceleration

- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode

Core:

- enable stable writes on inodes, replacing manually waiting for
writeback and allowing to skip that on inodes without checksums

- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary
since 5.8 where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole
infrastructure in the near future

- more folio API conversions and preparations for large folio support

- subpage cleanups and refactoring, split handling of data and
metadata to allow future support for large folios

- readpage works as block-by-block, no change for normal mode, this
is preparation for future subpage updates

- block group refcount fixes and hardening

- delayed iput fixes

- in zoned mode, fix zone activation on filesystem with missing
devices

Cleanups:

- inode parameter cleanups

- path auto-freeing updates

- code flow simplifications in send

- redundant parameter cleanups"

Merge tag 'for-6.13-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"Changes outside of btrfs: add io_uring command flag to track a dying
task (the rest will go via the block git tree).

User visible changes:

- wire encoded read (ioctl) to io_uring commands, this can be used on
itself, in the future this will allow 'send' to be asynchronous. As
a consequence, the encoded read ioctl can also work in non-blocking
mode

- new ioctl to wait for cleaned subvolumes, no need to use the
generic and root-only SEARCH_TREE ioctl, will be used by "btrfs
subvol sync"

- recognize different paths/symlinks for the same devices and don't
report them during rescanning, this can be observed with LVM or DM

- seeding device use case change, the sprout device (the one
capturing new writes) will not clear the read-only status of the
super block; this prevents accumulating space from deleted
snapshots

Performance improvements:

- reduce lock contention when traversing extent buffers

- reduce extent tree lock contention when searching for inline
backref

- switch from rb-trees to xarray for delayed ref tracking,
improvements due to better cache locality, branching factors and
more compact data structures

- enable extent map shrinker again (prevent memory exhaustion under
some types of IO load), reworked to run in a single worker thread
(there used to be problems causing long stalls under memory
pressure)

Core changes:

- raid-stripe-tree feature updates:
- make device replace and scrub work
- implement partial deletion of stripe extents
- new selftests

- split the config option BTRFS_DEBUG and add EXPERIMENTAL for
features that are experimental or with known problems so we don't
misuse debugging config for that

- subpage mode updates (sector < page):
- update compression implementations
- update writepage, writeback

- continued folio API conversions:
- buffered writes

- make buffered write copy one page at a time, preparatory work for
future integration with large folios, may cause performance drop

- proper locking of root item regarding starting send

- error handling improvements

- code cleanups and refactoring:
- dead code removal
- unused parameter reduction
- lockdep assertions"

btrfs: convert btrfs_buffered_write() to use folios

The buffered write path is still heavily utilizing the page interface.
Since we have converted it to do a page-by-page copying, it's much easier
to convert all involved functions to folio interface, this involves:

- btrfs_copy_from_user()
- btrfs_drop_folio()
- prepare_uptodate_page()
- prepare_one_page()
- lock_and_cleanup_extent_if_need()
- btrfs_dirty_page()

All function are changed to accept a folio parameter, and if the word
"page" is in the function name, change that to "folio" too.

The function btrfs_dirty_page() is exported for v1 space cache, convert
v1 cache call site to convert its page to folio for the new interface.

And there is a small enhancement for prepare_one_folio(), instead of
manually waiting for the page writeback, let __filemap_get_folio() to
handle that by using FGP_WRITEBEGIN, which implies
(FGP_LOCK | FGP_WRITE | FGP_CREAT | FGP_STABLE).

btrfs: make buffered write to copy one page a time

Currently the btrfs_buffered_write() is preparing multiple page a time,
allowing a better performance.

But the current trend is to support larger folio as an optimization,
instead of implementing own multi-page optimization.

This is inspired by generic_perform_write(), which is copying one folio
a time.

Such change will prepare us to migrate to implement the write_begin()
and write_end() callbacks, and make every involved function a little
easier.
