If timeevents.c is specific to clocks then maybe it should have : 'clock' in its name somehow? Right now having kern_et == kern_eventtimer.c : and timeevents.c is a bit ambiguous. Somehow making it clear that : timeevents.c is for clocks might help. Also, subr_ prefix helps prevent collisions in other parts of the tree for files with the same name. Warner
