[uml-devel] [patch] change ubd names

[Gerd Knorr <kraxel@bytesex.org>]

  Hi,

This patch renames the virtual block devices from ubd0,1,2 to
ubda,b,c (in /proc/partitions).  This is how they are named
in 2.4 kernels.  And this is IMHO better to number devices that
way because (a) hd + sd use the same scheme and (b) it is much
less confusing if you create partitions on your virtual block
devices.
