Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull vhost cleanups and fixes from Michael Tsirkin:
"Here are vhost cleanups and fixes by Asias He and myself. They affect
both vhost-net and vhost-scsi devices. They also *depend* on both
net-next and target-pending, where the net and target commits these
changes depend on are already merged. So merging through the common
vhost tree."
