From c1e6c8d074ea3621106548654cc244d2edc12ead Mon Sep 17 00:00:00 2001 From: Lee Schermerhorn Date: Mon, 14 Dec 2009 17:58:17 -0800 Subject: [PATCH] hugetlb: factor init_nodemask_of_node() Factor init_nodemask_of_node() out of the nodemask_of_node() macro. This will be used to populate the huge pages "nodes_allowed" nodemask for a single node when basing nodes_allowed on a preferred/local mempolicy or when a persistent huge page pool page count is modified via a per node sysfs attribute.
