Pull btrfs fixes from David Sterba:
"A few more fixes that arrived before the end of the year:
- a bunch of fixes related to transaction handle lifetime wrt various
operations (umount, remount, qgroup scan, orphan cleanup)
- async discard scheduling fixes
- fix item size calculation when item keys collide for extend refs
(hardlinks)
- fix qgroup flushing from running transaction
- fix send, wrong file path when there is an inode with a pending
rmdir
- fix deadlock when cloning inline extent and low on free metadata
space"
