Subject: [PATCH 04/14] sysfs: Use kill_anon_super
Date: Mon, 20 Aug 2007 21:36:29 +0900	[thread overview]
Message-ID: <11876133892681-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11876133893720-git-send-email-htejun-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Eric W. Biederman <ebiederm-aS9lmoZGLiVWk0Htik3J/w@public.gmane.org>

Since sysfs no longer stores fs directory information in the dcache
on a permanent basis kill_litter_super it is inappropriate and actively
wrong.  It will decrement the count on all dentries left in the
dcache before trying to free them.

At the moment this is not biting us only because we never unmount sysfs.
