File 0005-Manage.c-Only-issue-change-events-for-kernels-older-.patch of Package mdadm.7129

From 229e66cb9689ef20014ff8e5423316b19bfe6a11 Mon Sep 17 00:00:00 2001
From: Jes Sorensen <Jes.Sorensen@redhat.com>
Date: Tue, 16 Feb 2016 16:58:36 -0500
Subject: [PATCH 226/359] Manage.c: Only issue change events for kernels older
 than 2.6.28
References: fate#320107, fate#320291

2.6.28+ kernels handle this themselves and issuing the event here can
cause a race.
