Subject: [patch 6/14] s390: ccwgroup online attribute.
Date: Fri, 28 Oct 2005 16:08:09 +0200 [thread overview]
Message-ID: <20051028140809.GF7300@skybase.boeblingen.de.ibm.com> (raw)
From: Cornelia Huck <cohuck@de.ibm.com>
[patch 6/14] s390: ccwgroup online attribute.
Make the interface for setting ccw group devices on-/offline consistent with
that for ccw devices: Check if the device driver provided a set_{on,off}line
function and just set the device on-/offline if not.
