CC'ed Josh since he was testing this patchset.

I applied this patch set on top of 5.12, where it applied w/o any
patch conflicts, and I'm still seeing large number of crashes[1].  The
crashes are in a wide variety of tests, and many of the stack traces
involve the ext4_discard_work workqueue.

[1] I ran the test via "gce-xfstests ltm -c ext4/all -g auto --kernel
gs://<bucket>/kernel.deb", but almost all of the file system configs
were crashing.  So "kvm-xfstests -c ext4/4k -g auto" should be
sufficient to reproduce the problem.  kvm-xfstests can be found at
https://github.com/tytso/xfstests-bld.

I don't have time to debug this more closely right now, but at a rough
guess is that workqueue isn't properly getting shutdown during a file
system unmount, and this is causing all sorts of mischief.
