Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull vhost,virtio,vdpa bugfixes from Michael Tsirkin:
"Misc fixes all over the place.
Revert of virtio used length validation series: the approach taken
does not seem to work, breaking too many guests in the process. We'll
need to do length validation using some other approach"
[ This merge also ends up reverting commit f7a36b03a732 ("vsock/virtio:
suppress used length validation"), which came in through the
networking tree in the meantime, and was part of that whole used
length validation series - Linus ]
