[PATCH 00/18] virtiofs: Fix various races and cleanups round 1
Hi,
Michael Tsirkin pointed out issues w.r.t various locking related TODO

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
