Hi, I uploaded to mainline fix patch.
But I do not know it is right.

I thought of another way, how about below it?

How about it to change "flush_delayed_work" to "cancel_work_sync" or
"cancel_delayed_work_sync".
Then it will be wait until writeback workqueue done.
And "quota_release_work" function will queueing to events_unbound.
Because if "cancel_work_sync" is called, the second argument of "__flsuh work"
is called as true, and "check_flush_dependency" will be return normally, so it
is unlikely that there will be a problem.
