Subject: [PATCH 25/35] Monitor: fill devstate of containers based on supertype
Normally containers have no information in devstate. Volumes have states
of their members. To get state of all disks in container we use
load_super on container and create mdinfo list with all disk states.
We will use it later to find spares.
