Subject: [patch 1/4] mm, oom: ensure sysrq+f always passes valid zonelist
Date: Wed, 14 Nov 2012 01:15:19 -0800 (PST)	[thread overview]
Message-ID: <alpine.DEB.2.00.1211140111190.32125@chino.kir.corp.google.com> (raw)

With hotpluggable and memoryless nodes, it's possible that node 0 will
not be online, so use the first online node's zonelist rather than
hardcoding node 0 to pass a zonelist with all zones to the oom killer.
