Subject: [PATCH 1/8] mm: export get_vma_policy()
Date: Wed, 27 Apr 2011 19:35:42 -0400 [thread overview]
Message-ID: <1303947349-3620-2-git-send-email-wilsons@start.ca> (raw)
In-Reply-To: <1303947349-3620-1-git-send-email-wilsons@start.ca>
In commit 48fce3429df84a94766fbbc845fa8450d0715b48 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.
