Pull btrfs updates from David Sterba: "This contains feature updates, performance improvements, preparatory and core work and some related VFS updates: Features: - encoded read/write ioctls, allows user space to read or write raw data directly to extents (now compressed, encrypted in the future), will be used by send/receive v2 where it saves processing time - zoned mode now works with metadata DUP (the mkfs.btrfs default) - error message header updates: - print error state: transaction abort, other error, log tree errors - print transient filesystem state: remount, device replace, ignored checksum verifications - tree-checker: verify the transaction id of the to-be-written dirty extent buffer Performance improvements for fsync: - directory logging speedups (up to -90% run time) - avoid logging all directory changes during renames (up to -60% run time) - avoid inode logging during rename and link when possible (up to -60% run time) - prepare extents to be logged before locking a log tree path (throughput +7%) - stop copying old file extents when doing a full fsync() - improved logging of old extents after truncate Core, fixes: - improved stale device identification by dev_t and not just path (for devices that are behind other layers like device mapper) - continued extent tree v2 preparatory work - disable features that won't work yet - add wrappers and abstractions for new tree roots - improved error handling - add super block write annotations around background block group reclaim - fix device scanning messages potentially accessing stale pointer - cleanups and refactoring VFS: - allow reflinks/deduplication from two different mounts of the same filesystem - export and add helpers for read/write range verification, for the encoded ioctls" * tag 'for-5.18-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (98 commits) btrfs: zoned: put block group after final usage btrfs: don't access possibly stale fs_info data in device_list_add btrfs: add lockdep_assert_held to need_preemptive_reclaim btrfs: verify the tranisd of the to-be-written dirty extent buffer btrfs: unify the error handling of btrfs_read_buffer() btrfs: unify the error handling pattern for read_tree_block() btrfs: factor out do_free_extent_accounting helper btrfs: remove last_ref from the extent freeing code btrfs: add a alloc_reserved_extent helper btrfs: remove BUG_ON(ret) in alloc_reserved_tree_block btrfs: add and use helper for unlinking inode during log replay btrfs: extend locking to all space_info members accesses btrfs: zoned: mark relocation as writing fs: allow cross-vfsmount reflink/dedupe btrfs: remove the cross file system checks from remap btrfs: pass btrfs_fs_info to btrfs_recover_relocation btrfs: pass btrfs_fs_info for deleting snapshots and cleaner btrfs: add filesystems state details to error messages btrfs: deal with unexpected extent type during reflinking btrfs: fix unexpected error path when reflinking an inline extent ...
