Revision 8cd9da85d2bd87ce889043e7b1735723dd10eb89 authored by Frederic Weisbecker on 13 September 2021, 14:53:32 UTC, committed by Thomas Gleixner on 23 September 2021, 09:53:51 UTC
Resetting/stopping an itimer eventually leads to it being reprogrammed with an actual "0" value. As a result the itimer expires on the next tick, triggering an unexpected signal. To fix this, make sure that struct signal_struct::it[CPUCLOCK_PROF/VIRT]::expires is set to 0 when setitimer() passes a 0 it_value, indicating that the timer must stop.
