Merge tag 'for-5.16-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"A few more regression fixes and stable patches, mostly one-liners.
Regression fixes:
- fix pointer/ERR_PTR mismatch returned from memdup_user
- reset dedicated zoned mode relocation block group to avoid using it
and filling it without any recourse
Fixes:
- handle a case to FITRIM range (also to make fstests/generic/260
work)
- fix warning when extent buffer state and pages get out of sync
after an IO error
- fix transaction abort when syncing due to missing mapping error set
on metadata inode after inlining a compressed file
- fix transaction abort due to tree-log and zoned mode interacting in
an unexpected way
- fix memory leak of additional extent data when qgroup reservation
fails
- do proper handling of slot search call when deleting root refs"
* tag 'for-5.16-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: replace the BUG_ON in btrfs_del_root_ref with proper error handling
btrfs: zoned: clear data relocation bg on zone finish
btrfs: free exchange changeset on failures
btrfs: fix re-dirty process of tree-log nodes
btrfs: call mapping_set_error() on btree inode with a write error
btrfs: clear extent buffer uptodate when we fail to write it
btrfs: fail if fstrim_range->start == U64_MAX
btrfs: fix error pointer dereference in btrfs_ioctl_rm_dev_v2()
