Hi all,
I was wondering why some of my disks don't show up in /proc/stat's disk_io line. Specifically, my line says:
disk_io: (2,0):(144,144,288,0,0) (3,0):(35,35,140,0,0)
This equates to my floppy and first cdrom. I also have a second cdrom (RW) and 2 hard disks. Looking at the code (kstat_read_proc in fs/proc/proc_misc.c) it is looping only up to DK_MAX_MAJOR which is defined as 16 in kernel_stat.h. The problem is that my 2 HDs have a major number of 22.
I don't know enough to produce a patch, that is, what should DK_MAX_MAJOR be set to, but I believe the above is the problem.
Thanks,
--Rainer
