Merge tag 'ext4-for-linus-5.8-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull more ext4 updates from Ted Ts'o:
"This is the second round of ext4 commits for 5.8 merge window [1].
It includes the per-inode DAX support, which was dependant on the DAX
infrastructure which came in via the XFS tree, and a number of
regression and bug fixes; most notably the "BUG: using
smp_processor_id() in preemptible code in ext4_mb_new_blocks" reported
by syzkaller"
[1] The pull request actually came in 15 minutes after I had tagged the
rc1 release. Tssk, tssk, late.. - Linus
