Subject: [PATCH] sysfs/sysfs_read: Count active_disks and failed_disks
Git-commit: 64ec81da7a70adcdc0dbccaacc69aaf90edb4011
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

Cound active_disks as drives mark 'in_sync' and failed_disks as
disks marked 'faulty', in the same way ioctl(GET_ARRAY_INFO) does.
