Subject: [PATCH 1/3] kill sys_cred
Date: Mon, 29 Sep 2008 23:53:15 +0200 [thread overview]
Message-ID: <20080929215315.GA30363@lst.de> (raw)
capable_cred has been unused for a while so we can kill it and sys_cred.
That also means the cred argument to xfs_setattr and
xfs_change_file_space can be removed now.
