[akpm]

The patch titled
     Subject: oom-dont-assume-that-a-coredumping-thread-will-exit-soon-v2
has been removed from the -mm tree.  Its filename was
     oom-dont-assume-that-a-coredumping-thread-will-exit-soon-v2.patch

This patch was dropped because it was folded into oom-dont-assume-that-a-coredumping-thread-will-exit-soon.patch

------------------------------------------------------
From: Oleg Nesterov <oleg@redhat.com>
Subject: oom-dont-assume-that-a-coredumping-thread-will-exit-soon-v2

The patch is basically the same, but as Michal pointed out
mem_cgroup_out_of_memory() can use the new helper too, it can face the
same problems.
