The patch titled
oom: move constraints to enum
has been removed from the -mm tree. Its filename was
oom-move-constraints-to-enum.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: oom: move constraints to enum
From: David Rientjes <rientjes@xxxxxxxxxx>
The OOM killer's CONSTRAINT definitions are really more appropriate in an
enum, so define them in include/linux/oom.h.
Cc: Andrea Arcangeli <andrea@xxxxxxx>
