Default md-use-kzfree.patch removed from -mm tree

The patch titled
md: use kzfree()
has been removed from the -mm tree. Its filename was
md-use-kzfree.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: md: use kzfree()
From: Johannes Weiner <hannes@cmpxchg.org>

Use kzfree() instead of memset() + kfree().
