Subject: [PATCH 03/13] Remove path_release_on_umount()
Date: Mon, 22 Oct 2007 12:26:32 +0530	[thread overview]
Message-ID: <20071022065632.GD6489@in.ibm.com> (raw)
In-Reply-To: <20071022065352.GA6489@in.ibm.com>

From: Jan Blunck <jblunck@suse.de>

path_release_on_umount() should only be called from sys_umount(). I merged the
function into sys_umount() instead of having in in namei.c.
