[PATCH v3 0/6] vhost-vdpa multiqueue fixes

[Si-Wei Liu <si-wei.liu@oracle.com>]

Hi,

This patch series attempt to fix a few issues in vhost-vdpa multiqueue functionality.

Patch #1 and #2 are the formal submission for RFC patch in:
https://lore.kernel.org/qemu-devel/c3e931ee-1a1b-9c2f-2f59-cb4395c230f9@oracle.com/

Patch #3 through #5 are obviously small bug fixes. Please find the description of
each in the commit log.

Patch #6 is a workaround fix for the QEMU segfault described in:
https://lore.kernel.org/qemu-devel/4f2acb7a-d436-9d97-80b1-3308c1b396b5@oracle.com/


Thanks,
-Siwei

v3:
  - switch to LOG_GUEST_ERROR for guest trigger-able error
  - add temporary band-aid fix for QEMU crash due to recursive call
v2:
  - split off vhost_dev notifier patch from "align ctrl_vq index for non-mq
    guest for vhost_vdpa"
  - change assert to error message
  - rename vhost_vdpa_one_time_request to vhost_vdpa_first_dev for clarity

Si-Wei Liu (6):
  virtio-net: setup vhost_dev and notifiers for cvq only when feature is
    negotiated
  virtio-net: align ctrl_vq index for non-mq guest for vhost_vdpa
  vhost-vdpa: fix improper cleanup in net_init_vhost_vdpa
  vhost-net: fix improper cleanup in vhost_net_start
  vhost-vdpa: backend feature should set only once
  virtio-net: don't handle mq request in userspace handler for
    vhost-vdpa
