Subject: [PATCH] util/must_be_container: Use sysfs_read(GET_VERSION) to
 determine valid array
Git-commit: f5c924f441cedce2a13c48b12be35250560ee575
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

Use sysfs_read() instead of ioctl(RAID_VERSION) to determine this is
in fact a valid raid array fd.
