The patch titled
Subject: mm/mempolicy.c: fix mempolicy printing in numa_maps
has been removed from the -mm tree. Its filename was
mm-mempolicyc-fix-mempolicy-printing-in-numa_maps.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: David Rientjes <rientjes@xxxxxxxxxx>
Subject: mm/mempolicy.c: fix mempolicy printing in numa_maps
As a result of 5606e3877ad8 ("mm: numa: Migrate on reference policy"),
/proc/<pid>/numa_maps prints the mempolicy for any <pid> as "prefer:N" for
the local node, N, of the process reading the file.
This should only be printed when the mempolicy of <pid> 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.
