[Devel] [PATCH hci-8.1 0/2] vhost: replace VHOST_SET_NWORKERS with the mainstream worker ioctls

[Alexander Ivanov]

VHOST_SET_NWORKERS was added to run our userspace on the rh10 kernel
unchanged. It installs workers bypassing __vhost_vq_attach_worker(), so
VHOST_FREE_WORKER can destroy a worker still in use by a virtqueue.

Patch 1 reverts VHOST_SET_NWORKERS. Patch 2 lets vhost-blk use the
mainstream VHOST_NEW_WORKER/VHOST_ATTACH_VRING_WORKER ioctls instead,
like vhost-scsi does. Userspace has to be updated together with this
series.
