John Stultz c3a44b4d23 alarmtimers: Avoid possible denial of service with high freq periodic timers ... commit 6af7e471e5 upstream. Its possible to jam up the alarm timers by setting very small interval timers, which will cause the alarmtimer subsystem to spend all of its time firing and restarting timers. This can effectivly lock up a box. A deeper fix is needed, closely mimicking the hrtimer code, but for now just cap the interval to 100us to avoid userland hanging the system.
