VHOST_VSOCK_SET_RUNNING is used by the vhost vsock driver to perform
crucial VirtQueue initialisation, like assigning .private fields and
calling vhost_vq_init_access(), and clean up. However, this ioctl is
actually extremely useful for any vhost driver, that doesn't have a
side channel to inform it of a status change, e.g. upon a guest
reboot. This patch makes that ioctl generic, while preserving its
numeric value and also keeping the original alias.

I don't see it used in the next patches and as such should be part of another
series.
It isn't used in the next patches, it is used in this patch - see below.
Thanks
