Subject: [PATCH 2/8] Mark powerpc memory resources as busy
Date: Wed, 24 Jul 2013 13:36:34 -0500 [thread overview]
Message-ID: <51F01EB2.9060802@linux.vnet.ibm.com> (raw)
In-Reply-To: <51F01E06.6090800@linux.vnet.ibm.com>
Memory I/O resources need to be marked as busy or else we cannot remove
them when doing memory hot remove.
