md: notify about new spare disk in the container
In case of external metadata arrays spare disks are added to containers first. mdadm keeps monitoring /proc/mdstat output and when spare disk is available, it moves it from the container to the array. The problem is there is no notification of new spare disk in the container and mdadm waits a long time (until timeout) before it takes the action.
