That's probably best. We don't expect the list for one parent to get
very long (so checking for previous addition should be quick), and this

Otherwise we might end up sleeping on a kmalloc while holding the lock.
At least that's my take. Does anyone feel the writelock should just be
held for all of audit_create_watch()?
