==> Regarding [PATCH] autofs4 - post expire race fix; raven@themaw.net adds:
raven> At the tail end of an expire it's possible for a process to enter raven> autofs4_wait, with a waitq type of NFY_NONE but find that the expire raven> is finished. In this cause autofs4_wait will try to create a new raven> wait but not notify the daemon leading to a hang. As the wait type raven> is meant to delay mount requests from revalidate or lookup during an raven> expire and the expire is done all we need to do is check if the raven> dentry is a mountpoint. If it's not then we're done.
FWIW, this looks good to me. (sorry for the late reply)
