From 8790c71a18e5d2d93532ae250bcf5eddbba729cd Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Thu, 30 Jan 2014 15:46:08 -0800 Subject: [PATCH] mm/mempolicy.c: fix mempolicy printing in numa_maps As a result of commit 5606e3877ad8 ("mm: numa: Migrate on reference policy"), /proc//numa_maps prints the mempolicy for any as "prefer:N" for the local node, N, of the process reading the file. This should only be printed when the mempolicy of is MPOL_PREFERRED for node N. If the process is actually only using the default mempolicy for local node allocation, make sure "default" is printed as expected.
