From 8b1b1eb521004cec2518307c22dba8f4bff1c2bf Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Wed, 20 Aug 2014 23:20:09 +0530 Subject: decnet: Use time_after_eq The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. A simplified version of the Coccinelle semantic patch making this change is as follows: @change@ expression E1,E2; @@ - (jiffies - E1) >= E2 + time_after_eq(jiffies, E1+E2) Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: David S.
