From 1f5a24794a54588ea3a9efd521be31d826e0b9d7 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Thu, 9 Dec 2010 12:02:18 -0800 Subject: timers: Rename timerlist infrastructure to timerqueue Thomas pointed out a namespace collision between the new timerlist infrastructure I introduced and the existing timer_list.c So to avoid confusion, I've renamed the timerlist infrastructure to timerqueue.
