Re: [RFCI] How best to partition MD/raid devices in 2.6

This brings up a tangent point...  partitions on top of RAID are a new
thing, which means that one has the chance to define the partition
format.

And I kinda like EFI partition format, a lot better than the other
common ones...

Any reason why the current partition-mapping code couldn't be extended
to handle partition detection on a generic block device (which is what
MD presents I think) instead of a struct gendisk?  Then it wouldn't
matter which scheme someone wanted to use - any scheme provided for in
the kernel (or userspace if partx were extended) could be used.

I'm partial to the EFI format too, but wouldn't want to write that
code a second time, once for normal disks, and once for md.

Thanks,
Matt

Any block_device has a gendisk - md.c ones included.  The problem is where
to put device numbers of partitions.
