Subject: [PATCH 3/5 v2] Export memory_sysdev_class
Date: Fri, 18 Sep 2009 10:02:26 -0500 [thread overview]
Message-ID: <4AB3A102.90406@austin.ibm.com> (raw)
In-Reply-To: <4AB39FB3.1020608@austin.ibm.com>
Export the memory_sysdev_class structure. This is needed so we can create
a 'release' file in sysfs in addition to the existing 'probe' file in
order to support DLPAR removal of memory on the powerpc/pseries platform.
The new 'release' file will be powerpc/pseries only.
