The patch titled
xfs: remove useless wmb() memory barrier
has been removed from the -mm tree. Its filename was
xfs-remove-useless-wmb-memory-barrier.patch

------------------------------------------------------
Subject: xfs: remove useless wmb() memory barrier
From: Ralf Baechle <ralf@xxxxxxxxxxxxxx>
wake_up's implementation does an implicit memory barrier and I think that's
the only sane semantics as the caller shouldn't have to worry. So this
write memory barrier is useless.
