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"
