Thomas Gleixner 2860d4d315 posix-timers: Drop signal if timer has been deleted or reprogrammed ... No point in delivering a signal from the past. POSIX does not specify the behaviour here: - "The effect of disarming or resetting a timer with pending expiration notifications is unspecified." - "The disposition of pending signals for the deleted timer is unspecified." In both cases it is reasonable to expect that pending signals are discarded. Especially in the reprogramming case it does not make sense to account for previous overruns or to deliver a signal for a timer which has been disarmed. Drop the signal as that is conistent and understandable behaviour.
