[PATCH] Switch getnstimestamp() calls to ktime_get_ts()
Matt Helsley [Tue, 10 Jan 2006 04:52:40 +0000 (20:52 -0800)]
Use ktime_get_ts() to take the timestamp instead of getnstimestamp().  This
patch prepares to remove getnstimestamp() by switching its only user to a
different function with almost exactly the same code.
