Um, what you've just posted agrees with what I wrote, and with what I've
read.
hdb1 is the first partition on the slave device of the first IDE chain in
the system. Minor number 3 is the first IDE chain. Offset 64 is the slave
device. +1 for the first partition. So (3,41) would be before on the master
device of the same chain, no? And block major device 22 would be the second
IDE chain. This agrees with the behavior of MAKEDEV on my system (RHL 6.1).
I'm looking at Documentation/devices.txt in the kernel source, and my own
/dev/ directory.
