Hello,
When running fstests, I've hit a deadlock with generic/530 test with
5.3-rc6 based kernel (commit 9e8312f5e160 in particular) in my test VM.
Full dmesg is attached. BTW mount is the only task in D state. In
particular all xfs kernel processes are happily sitting in interruptible
sleep.

Hm, is this possibly the same as:

(Something about needing to nudge the log along when dumping unlinked
inodes during log recovery?)

Yeah. Looks like that. Thanks for the pointer.
