This looks dubious What about using kfree_rcu() instead ?
It would lead to unbound allocation from userspace.
translate_desc() still uses rcu_read_lock(), its not clear if the mutex is really held.
Yes, vhost_get_vq_desc must be called with the vq mutex held. The rcu_read_lock/unlock in translate_desc is unnecessary.
