Subject: Re: [PATCH] autofs4 - post expire race fix
Date: Wed, 15 Jun 2005 20:07:15 -0400	[thread overview]
Message-ID: <17072.49843.360761.694530@segfault.boston.redhat.com> (raw)
In-Reply-To: <Pine.LNX.4.62.0506041528070.8502@donald.themaw.net>

==> 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)

Thanks,

Jeff
