commit f56916b97fe2031761ca611f0a342efd913afb33 Author: Chuck Lever <[email protected]> Date: Fri May 7 13:34:37 2010 -0400 ktime: introduce ktime_to_ms() To report ktime statistics to user space in milliseconds, a new helper is required. When considering how to do this conversion, I didn't immediately see why the extra step of converting ktime to a timeval was needed. To make that more clear, introduce a couple of large comments.
