From 2b7bddf06c30da08f8d6270b40f0d382c1c5fc6e Mon Sep 17 00:00:00 2001
From: Jes Sorensen <jsorensen@fb.com>

Subject: [PATCH] kernel-patch: Remove obsolete kernel patches against 2.6
Git-commit: 2b7bddf06c30da08f8d6270b40f0d382c1c5fc6e
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

While we still support some of these kernels, I do not think it makes
sense to carry this patches around at this point.

-Support adding a spare to a live md array with external metadata.
