From 5966514db662fb24c9bb43226a80106bcffd51f8 Mon Sep 17 00:00:00 2001 From: Paul Jackson Date: Sun, 8 Jan 2006 01:01:47 -0800 Subject: [PATCH] cpuset: mempolicy one more nodemask conversion Finish converting mm/mempolicy.c from bitmaps to nodemasks. The previous conversion had left one routine using bitmaps, since it involved a corresponding change to kernel/cpuset.c Fix that interface by replacing with a simple macro that calls nodes_subset(), or if !CONFIG_CPUSET, returns (1).
