Subject: [RFC v5 3/6] migration/dlpar: Add device readd queuing function
Date: Tue, 22 May 2018 18:36:40 -0500 [thread overview]
Message-ID: <834f1932-68f6-07bb-d1c1-47bee7eb582a@linux.vnet.ibm.com> (raw)
In-Reply-To: <4b1138ff-4ca0-bdce-26cc-b42191258017@linux.vnet.ibm.com>
migration/dlpar: This patch adds function dlpar_readd_action()
which will queue a worker function to 'readd' a device in the
system. Such devices must be identified by a 'resource' type
and a drc_index to be readded.
