Message-Id: <20070205182242.12164.33021.sendpatchset@ermintrude.int.wirex.com>
Date: Mon, 05 Feb 2007 10:22:42 -0800

Subject: [RFC 3/28] Pass struct file down to remove_suid and children
Pass struct file down to remove_suid and children
Pass struct path to remove_suid and should_remove_suid instead of
only the dentry. Required by a later patch that adds a struct
vfsmount parameter to notify_change().
