[Qemu-devel] [PATCH 0/4] Small vhost-user fixes and tweaks

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Hi,
  This set has a small set of fixes for vhost-user and also
  enables the SET_SLAVE_REQ_FD feature in libvhost-user.
  (Where it just stashes the fd).

Dave
