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
