Hi. I see "/proc/sys/kernel/sched_granularity_ns" mentioned on web sites 
and such, but I do have this file and cannot create it. Yes, I am root 
and /proc is mounted. Are there boot parameters that I must enable to 
tune this variable? Do I need to specifically enable this in .config?

I am using 2.6.23-rc2.

Thanks,
Dan

Sorry for the dumb question--I searched the source and found that 
CONFIG_SCHED_DEBUG must be defined, and after enabling kernel debugging, 
this was automatically turned on. I didn't realize that this type of 
tuning was considered debugging.

Thanks,
Dan
