From: S.Caglar Onur Date: Fri, 28 Mar 2008 21:41:24 +0000 (-0700) Subject: drivers/net/arcnet/arcnet.c: use time_* macros X-Git-Tag: v2.6.26-rc1~1138^2~270^2~11 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9307b570a745da4f2d83195f5337927e98221bb2;p=linux-2.6 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.
