I'm a bit confused about fiq->priv's role in this. The callback takes
struct fuse_iqueue *fiq as the argument, not void *priv, so it could
theoretically do more than just release priv.
I think one of the following would be clearer:
/**
* Drop a reference to fiq->priv.

[PATCH 14/18] virtiofs: Add a fuse_iqueue operation to put() reference
Soon I will make virtio_fs object reference counted, where reference will
be taken by device as well as by fuse_conn (fuse_conn->fuse_iqueue->fiq_priv).
When fuse_connection is going away, it should put its reference on virtio_fs
object.
So add a fuse_iqueue method which can be used to call into virtio_fs to
put the reference on the object (fiq_priv).

[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
