[PATCH] dev_t handling cleanups (12/12)
added the exclusion between ADD_PARTITION/DELETE_PARTITION/open() (BLKPG
ioctls didn't grab ->bd_sem when they should have).
added bdev->bd_part; it is set at open() to point to the hd_struct of
partition in question, reset on final close.
blk_partition_remap() uses ->bd_part instead of the current mess
->bd_offset is gone, we use ->bd_part->start_sect instead
added missing ->release() to hd_struct kobject, moved kfree() into it
->bd_part cotributes to refcount of hd_struct - we bump it when
->bd_part is set and drop when it's reset.
