Merge tag 'for-5.17-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
- yield CPU more often when defragmenting a large file
- skip defragmenting extents already under writeback
- improve error message when send fails to write file data
- get rid of warning when mounted with 'flushoncommit'
* tag 'for-5.17-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: send: in case of IO error log it
btrfs: get rid of warning on transaction commit when using flushoncommit
btrfs: defrag: don't try to defrag extents which are under writeback
btrfs: don't hold CPU for too long when defragging a file
