sched/numa: Remove the numa_balancing_scan_period_reset sysctl

2013-10-09T12:48:18+00:00

With scan rate adaptions based on whether the workload has properly
converged or not there should be no need for the scan period reset
hammer. Get rid of it.

hung_task: Change sysctl_hung_task_check_count to 'int'

2013-09-23T09:10:49+00:00

As 'sysctl_hung_task_check_count' is 'unsigned long' when this
value is assigned to max_count in check_hung_uninterruptible_tasks(),
it's truncated to 'int' type.

This causes a minor artifact: if we write 2^32 to sysctl.hung_task_check_count,
hung task detection will be effectively disabled.

With this fix, it will still truncate the user input to 32 bits, but
reading sysctl.hung_task_check_count reflects the actual truncated value.

sched: move RR_TIMESLICE from sysctl.h to rt.h

2013-02-22T17:20:11+00:00

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)

sched/rt: Add a tuning knob to allow changing SCHED_RR timeslice

2013-02-07T19:51:07+00:00

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).

sched: Move sched.h sysctl bits into separate header

2013-02-07T19:50:54+00:00

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.
