From 420635f517cf1bb8929caf80ce5a30e827b9df42 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 19 Apr 2008 18:14:50 -0700 Subject: [PATCH] drivers/atm: use time_before, time_before_eq, etc 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 semantic patch making this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @ change_compare_np @ expression E; @@ ( - jiffies <= E + time_before_eq(jiffies,E) | - jiffies >= E + time_after_eq(jiffies,E) | - jiffies < E + time_before(jiffies,E) | - jiffies > E + time_after(jiffies,E) ) @ include depends on change_compare_np @ @@ #include @ no_include depends on !include && change_compare_np @ @@ #include + #include // Signed-off-by: Julia Lawall Signed-off-by: Andrew Morton Signed-off-by: David S.
