> > From: Bean Huo <beanhuo@xxxxxxxxxx> > > This patch is to change msleep() to usleep_range() based on > Documentation/timers/timers-howto.txt. It suggests using > usleep_range() for small msec(1ms - 20ms) since msleep() > will often sleep longer than desired value. > > After changing, booting time will be 5ms-10ms faster than before. > I tested this change on two different platforms, one has 5ms faster, > another one is about 10ms.
