[PATCH] jiffies: add time comparison functions for 64 bit jiffies

From: Jason A. Donenfeld
Date: Wed Sep 28 2016 - 23:33:52 EST

Though the time_before and time_after family of functions were nicely
extended to support jiffies64, so that the interface would be
consistent, it was forgotten to also extend the before/after jiffies
functions to support jiffies64. This commit brings the interface to
parity between jiffies and jiffies64, which is quite convenient.

* Have the 32 bit jiffies value wrap 5 minutes after boot
