From bd858e84d4a179c3030dccba56efb6a93e455c10 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Thu, 10 Jul 2014 18:14:20 +0200 Subject: [PATCH] s390/kdump: Return NOTIFY_OK for all actions other than MEM_GOING_OFFLINE We only have to check kdump memory for the MEM_GOING_OFFLINE action. Therefore skip the test and return NOTIFY_OK for all other memory hotplug actions.
