v3:
- Fix sepc -> spec typo in Patch 1 [Stefano]
- Check for a -1 fd in Patch 2 [Stefano]
- Handle failure with vu_panic() instead of incorrect return -1 in Patch 2 [Stefano]
- Add eventfd_write() EINTR and EAGAIN handling in Patch 2

Jorge Moreira <jemoreira@google.com> pointed out that the ring state machine is
underspecified. This patch series updates the spec to clarify how the ring
state machine works, makes libvhost-user spec-compliant, and improves the
compatibility of QEMU's vhost-user front-end.

Stefan Hajnoczi (3):
  vhost-user.rst: clarify when rings are started
  libvhost-user: look for available vq buffers upon SET_VRING_KICK
  vhost-user: inject kick after SET_VRING_KICK
