File 0132-Monitor-check_array-Get-nr_disks-active_disks-and-sp.patch of Package mdadm.7989

From b98943a4f889b466a3d07264068042b18c620d33 Mon Sep 17 00:00:00 2001
From: Jes Sorensen <jsorensen@fb.com>

Subject: [PATCH] Monitor/check_array: Get nr_disks, active_disks and
 spare_disks from sysfs
Git-commit: b98943a4f889b466a3d07264068042b18c620d33
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

This leaves working_disks and utime missing before we can eliminate
check_array()'s call to md_get_array_info()
