[PATCH] preparation to use of driverfs refcounts, part 2 - disk
* disk->disk_dev is initialized in alloc_disk(), device_add()'d in
add_disk(), device_del()'d in unregister_disk() and device_put() in
put_disk().
* devices of partitions are made its children.
* attributes of disk one: dev (dev_t of the thing), range (number of
minors) and size (in sectors).
* attributes of partition ones: dev (ditto), start (in sectors) and
size (in sectors).
* disk devices are put on a new bus - "block"
* if caller of add_disk() had set disk->driverfs_dev, we set symlinks:
"device" from disk to underlying device and "block" from underlying
device to disk.
* ->release() of disk_dev frees disk and disk->part.
At that point we have sane driverfs subtree for each gendisk and
refcount of its root (disk->disk_dev) can act as gendisk refcount.
