Subject: posix-timers: do_schedule_next_timer: fix the setting of ->si_overrun
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=54da1174922cddd4be83d5a364b2e0fdd693f513;p=linux-beck.git

posix-timers: do_schedule_next_timer: fix the setting of ->si_overrun

do_schedule_next_timer() sets info->si_overrun = timr->it_overrun_last,
this discards the already accumulated overruns.
