Thanks for splitting this out of your other 9p improvements!

I was about to ask Peter/Ingo which tree this should go through, but
could you also convert the other few wait_event_killable() calls in
net/9p/trans_*.c ?
They're either waiting for other IO to complete (virtio x2) or for the
current IO to complete (virtio/xen), so I think they qualify just as
much.

(the virtio ones will likely conflict with some other rework that's been
dragging on last month, but given the patch is trivial it won't matter
much, you can send as of master)

Thanks,
