how often, if at all, will this get returned to the default value?

every reboot?

every upgrade of kernel?

of some module?

when i do a cat, it returns this:

NEW_FAIR_SLEEPERS NORMALIZED_SLEEPER WAKEUP_PREEMPT START_DEBIT
AFFINE_WAKEUPS CACHE_HOT_BUDDY SYNC_WAKEUPS NO_HRTICK NO_DOUBLE_TICK
ASYM_GRAN LB_BIAS LB_WAKEUP_UPDATE ASYM_EFF_LOAD NO_WAKEUP_OVERLAP
LAST_BUDDY

has it been overwritten already, by a reboot? it looks like it has

cheers
