Hm, there's a weirdness here: if freezer_delta != 0 when alarmtimer_suspend()
is
called then type might be '0', although it's not alarm_bases[0] this value is
picked up from.
Wouldn't it be better to initialize 'type' to -1 instead? (And rename it to
min_type or so.)
That would disambiguate the freezer_delta special case in the trace.
(Unless I missed something.)
Thanks,
Ingo
