for it. I'd prefer it fixed but its arguable that device mapper is the
right way to punt all our partitioning to userspace.

Now when we have 20-bit minors, can't we simply recycle some of the
higher bits for additional partitions, across the board? 63 partitions

15 partitions (at least for sd_mod devices) are too few.
So I tried the following: after scanning the disk (sda), when we know
the number of partitions P on a disk, create a new block device
/dev/gd0 that is a copy of sda (in terms of disk->queue, etc.). This
is done using alloc_disk(P).
