Subject: [PATCH] mdopen/open_mddev: Use md_get_array_info() to determine valid
 array
Git-commit: 40b054e1dc9e334621fd2081bf6fc46b01dd7ef4
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

md_get_array_info() can be used instead of md_get_version() to
determine this is in fact a valid array.
