Using a dynamic major number is the way to go, though.

Partition scanning by the kernel has nothing to do with that.

It depends on the registration of the block device or gendisk (IIRC
there's a flag for that, that's why it doesn't work for /dev/loop); if
the kernel finds a recognized partition table format, it will scan for
partitions.

nfblock does use alloc_disk(16), and sets dev->disk->first_minor =
dev_id * 16, so there should be space for 15 partitions.

Note that I haven't tried nfblock myself. I did a quick compare with
ps3disk (which is quite simple and which I know does support
partitions), but didn't see anything obvious.
