[PATCH] md: extend md sysfs support to component devices.
Each device in an md array how has a corresponding
/sys/block/mdX/md/devNN/
directory which can contain attributes. Currently there is only 'state' which
summarises the state, nd 'super' which has a copy of the superblock, and
'block' which is a symlink to the block device.
Also, /sys/block/mdX/md/rdNN represents slot 'NN' in the array, and is a
symlink to the relevant 'devNN'. Obviously spare devices do not have a slot
in the array, and so don't have such a symlink.
