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 This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ 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) ) @ include depends on change_compare_np @ @@ #include <linux/jiffies.h> @ no_include depends on !include && change_compare_np @ @@ #include <linux/...> + #include <linux/jiffies.h> // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: Alessandro Zummo <a.zummo@xxxxxxxxxxxx> Cc: David Brownell <david-b@xxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/char/rtc.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff -puN drivers/char/rtc.c~drivers-char-rtcc-use-time_before-time_before_eq-etc drivers/char/rtc.c --- a/drivers/char/rtc.c~drivers-char-rtcc-use-time_before-time_before_eq-etc +++ a/drivers/char/rtc.c @@ -88,6 +88,7 @@ #ifdef CONFIG_SPARC32 #include <linux/pci.h> +#include <linux/jiffies.h> #include <asm/ebus.h> static unsigned long rtc_port; @@ -1316,7 +1317,8 @@ void rtc_get_rtc_time(struct rtc_time *r * Once the read clears, read the RTC time (again via ioctl).
