Description of problem:
Request to increase DK_MAX_MAJOR in include/linux/kernel_stat.h 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Request to increase DK_MAX_MAJOR in include/linux/kernel_stat.h from 99 to 
255.  This would allow for tracking of iostat performance metrix for pseudo 
devices that have major numbers greater than 99.

What devices is this? Are the device numbers assigned by lanana ?
Comment 2 Heather Conway 2002-12-17 09:25:51 EST
Our PowerPath developers are using major numbers 232-239 for our PowerPath 
multi-pathing product.  
I'm not familiar with Ianana....what is it?

Arjan, Heather asks "I'm not familiar with Ianana....what is it?"
Comment 4 Matt Domsch 2003-04-28 11:48:54 EDT
lanana is the Linux Assigned Names and Numbers Authority, who assigns the
major/minor space for device nodes, as published on www.lanana.org and
linux/Documentation/devices.txt.  That's who you go to to offically request
major/minor numbers for your devices.

In kernel 2.4.9-e.18 DK_MAX_MAJOR is still 99, thus this won't be fixed in the
Q2 errata.
Comment 5 Matt Domsch 2004-11-22 18:25:57 EST
Heather, is this bug still relevant?
RHEL2.1 Update 6 Public Beta kernel 2.4.9-e.51 still has DK_MAX_MAJOR
set to 99.  RHEL2.1 Update 7 is closed to all but Sev. 1 bugs, and
there aren't any little-fix Updates planned.

Can you close this as WONTFIX, given that it hasn't been, and won't be?
