From 909d75a3b77bdd8baa9429bad3b69a654d2954ce Mon Sep 17 00:00:00 2001 From: Paul Jackson Date: Sun, 8 Jan 2006 01:01:55 -0800 Subject: [PATCH] cpuset: implement cpuset_mems_allowed Provide a cpuset_mems_allowed() method, which the sys_migrate_pages() code needed, to obtain the mems_allowed vector of a cpuset, and replaced the workaround in sys_migrate_pages() to call this new method.
