From 9307b570a745da4f2d83195f5337927e98221bb2 Mon Sep 17 00:00:00 2001 From: "S.Caglar Onur" Date: Fri, 28 Mar 2008 14:41:24 -0700 Subject: drivers/net/arcnet/arcnet.c: use time_* macros The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So use the time_after() macro, defined in linux/jiffies.h, which deals with wrapping correctly.
