[PATCH] hrtimers: move default_timer_slack_ns to system-wide sysctl

2012-01-27 Thread Dmitry Antipov
- moving default_timer_slack_ns from per-task field to global variable controlled via sysctl() in [0..100] range (usecs) provides some more system-wide control beyond per-task prctl(); - task_time_slack() should be used to get default timer slack if no special requirements exists.
