Merge tag 'for-5.19-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba: - zoned relocation fixes: - fix critical section end for extent writeback, this could lead to out of order write - prevent writing to previous data relocation block group if space gets low - reflink fixes: - fix race between reflinking and ordered extent completion - proper error handling when block reserve migration fails - add missing inode iversion/mtime/ctime updates on each iteration when replacing extents - fix deadlock when running fsync/fiemap/commit at the same time - fix false-positive KCSAN report regarding pid tracking for read locks and data race - minor documentation update and link to new site * tag 'for-5.19-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Documentation: update btrfs list of features and link to readthedocs.io btrfs: fix deadlock with fsync+fiemap+transaction commit btrfs: don't set lock_owner when locking extent buffer for reading btrfs: zoned: fix critical section of relocation inode writeback btrfs: zoned: prevent allocation from previous data relocation BG btrfs: do not BUG_ON() on failure to migrate space when replacing extents btrfs: add missing inode updates on each iteration when replacing extents btrfs: fix race between reflinking and ordered extent completion
