From 1dc75956663661e6bfee7836ddd2def2f66745b9 Mon Sep 17 00:00:00 2001 From: John Allen Date: Thu, 7 Jul 2016 10:05:52 -0500 Subject: [PATCH] powerpc/pseries: Use kernel hotplug queue for PowerVM hotplug events The sysfs interface used to handle PowerVM hotplug events should use the hotplug queue as well. PRRN events will soon be placing many hotplug events on the queue at once and we will need ordinary hotplug events to use the queue as well in order to ensure these events will still be handled and that proper serialization is maintained during the PRRN event.
