#     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()
