...something.
2. thread0 does VHOST_SET_OWNER ioctl. This calls vhost_task_create() to
create the task_struct which runs the vhost_worker() function which handles
the work->fns.
3. If userspace now does a SIGKILL or just exits without doing a close() on
/dev/vhost-$something, then when thread0 does exit_files() that will do the
fput that does vhost-$something's file_operations->release.

So, at least in this simple case vhost_worker() can just exit after SIGKILL,
and thread0 can flush the outstanding commands when it calls vhost_dev_flush()
rather than wait for vhost_worker().
Right?

Yes, but probably SIGABRT/exit doesn't really differ from SIGKILL wrt
vhost_worker().

Ah. thanks. I confused CLONE_FS in vhost_task_create() with CLONE_FILES.
