Hi,

Here is the (sd) patch to support > 4000 disks on 32-bit dev_t work
in 2.5.67-mm tree.

This patch addresses the backward compatibility with device nodes
issue. All the new disks will be addressed by only last major.

SCSI has 16 majors. Each major supports 16 disks currently.
This patch leaves this assumption for first 15 majors and all the
new disks addressable by 32/64 dev_t work will be added to
SCSI last major#. This way, we don't need to create device
nodes in /dev, if you switch between 2.4 and 2.5.

Any comments ?

Thanks,
Badari
