[PATCH 11/18] virtiofs: stop and drain queues after sending DESTROY
During virtio_kill_sb() we first stop forget queue and drain it and then
call fuse_kill_sb_anon(). This will result in sending DESTROY request to
fuse server. Once finished, stop all the queues and drain one more time
just to be sure and then free up the devices.
Given drain queues will call flush_work() on various workers, remove this
logic from virtio_free_devs().

[PATCH 00/18] virtiofs: Fix various races and cleanups round 1
Hi,
Michael Tsirkin pointed out issues w.r.t various locking related TODO
items and races w.r.t device removal.
In this first round of cleanups, I have taken care of most pressing
issues.
These patches apply on top of following.
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git#virtiofs-v4
I have tested these patches with mount/umount and device removal using
qemu monitor. For
