Patrick Pannuto 0fcb80818b Documentation: Add timers/timers-howto.txt ... This file seeks to explain the nuances in various delays; many driver writers are not necessarily familiar with the various kernel timers, their shortfalls, and quirks. When faced with ndelay, udelay, mdelay, usleep_range, msleep, and msleep_interrubtible the question "How do I just wait 1 ms for my hardware to latch?" has the non-intuitive "best" answer: usleep_range(1000,1500) This patch is followed by a series of checkpatch additions that seek to help kernel hackers pick the best delay.
