The patch titled
     drivers/char/rtc.c: use time_before, time_before_eq, etc
has been removed from the -mm tree.  Its filename was
     drivers-char-rtcc-use-time_before-time_before_eq-etc.patch

Subject: drivers/char/rtc.c: use time_before, time_before_eq, etc
From: Julia Lawall <julia@xxxxxxx>

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/)

// <smpl>
@ 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)
)
