Subject: [PATCH] Detail: differentiate between container and inactive arrays
Git-commit: bb8354598676428af01f23bfb1876c7356d61147
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

Containers used to be handled as active arrays because GET_ARRAY_INFO
ioctl returns valid structure for them. As containers appear as inactive
in sysfs, the output for detail command has changed.

Stop relying on inactive state for containers. Make the output look the
same as in mdadm 4.0.
