RE: /proc/stat missing disk_io info

[Rainer Mager]

Not to be pushy or anything but since I received zero responses to this I
was wondering what else I can do. I'd be happy to patch the problem myself
but I have no idea what the correct value for DK_MAX_MAJOR  should be.

Anywho, if anyone has any thoughts I'd appreciate them.
