Subject: sysfs/sysfs_read: Count active_disks and failed_disks
X-Git-Tag: mdadm-4.1-rc1~152
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64ec81da7a70adcdc0dbccaacc69aaf90edb4011;p=thirdparty%2Fmdadm.git

sysfs/sysfs_read: Count active_disks and failed_disks

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