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
