From b3b8128fd3b0966830ee90f1162173d07cb496a0 Mon Sep 17 00:00:00 2001 From: "Robert P. J. Day" Date: Wed, 16 Apr 2008 21:09:28 -0700 Subject: [PATCH] IB/ipath: Fix time comparison to use time_after_eq() Raw comparison against jiffies will fail if jiffies wraps, although since ipath currently only supports 64-bit architectures, this is rather far-fetched. Still, it's better to use time_after_eq(). Signed-off-by: Robert P. J.
