From: Paolo 'Blaisorblade' Giarrusso <[email protected]>
To rethink locking, I needed to understand well what each function does. While
doing this I renamed some:
* ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev)
* ubd_new_disk -> ubd_disk_register (it handles registration with the block
layer - one hopes this makes clearer the difference with ubd_add())
