From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) 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: Always 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. Additional info:
What devices is this? Are the device numbers assigned by lanana ?
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?"
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.
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? -Matt
