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"
