[PATCH] alloc_disk/put_disk
Beginning of proper refcounting. New helpers introduced, several drivers
switched to using them for dynamic allocation of gendisks. Once everything
is switched (and that will be way easier than per-drive gendisks series)
we will be able to add sane reference counts on gendisk, at which point
we can safely put pointer to gendisk in struct block_device / struct request
and we had pretty much won - from that point it's pretty straightforward
crapectomy in drivers.
