Merge tag 'for-5.5-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"A mix of regression fixes and regular fixes for stable trees:
- fix swapped error messages for qgroup enable/rescan
- fixes for NO_HOLES feature with clone range
- fix deadlock between iget/srcu lock/synchronize srcu while freeing
an inode
- fix double lock on subvolume cross-rename
- tree log fixes
* fix missing data checksums after replaying a log tree
* also teach tree-checker about this problem
* skip log replay on orphaned roots
- fix maximum devices constraints for RAID1C -3 and -4
- send: don't print warning on read-only mount regarding orphan
cleanup
- error handling fixes"
