From d98f6cb67fb5b9376d4957d7ba9f32eac35c2e08 Mon Sep 17 00:00:00 2001 From: Stephen Wilson Date: Tue, 24 May 2011 17:12:41 -0700 Subject: [PATCH] mm: export get_vma_policy() In commit 48fce3429d ("mempolicies: unexport get_vma_policy()") get_vma_policy() was marked static as all clients were local to mempolicy.c. However, the decision to generate /proc/pid/numa_maps in the numa memory policy code and outside the procfs subsystem introduces an artificial interdependency between the two systems. Exporting get_vma_policy() once again is the first step to clean up this interdependency.
