Clark Williams	bc681593b5	sched: move RR_TIMESLICE from sysctl.h to rt.h ... Originally submitted by Clark Williams as part of a cleanup, but happens also to fix an ia64 build problem: arch/ia64/kernel/init_task.c:38: error: 'RR_TIMESLICE' undeclared here (not in a function) Signed-off-by: Clark Williams <clark.williams@gmail.com> Signed-off-by: Tony Luck <tony.luck@intel.com>	2013-02-22 09:20:11 -08:00
Clark Williams	ce0dbbbb30	sched/rt: Add a tuning knob to allow changing SCHED_RR timeslice ... Add a /proc/sys/kernel scheduler knob named sched_rr_timeslice_ms that allows global changing of the SCHED_RR timeslice value. User visable value is in milliseconds but is stored as jiffies. Setting to 0 (zero) resets to the default (currently 100ms).

Clark Williams	cf4aebc292	sched: Move sched.h sysctl bits into separate header ... Move the sysctl-related bits from include/linux/sched.h into a new file: include/linux/sched/sysctl.h. Then update source files requiring access to those bits by including the new header file.
