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> --- diff -r -u -p a/drivers/atm/iphase.c b/drivers/atm/iphase.c --- a/drivers/atm/iphase.c 2007-09-09 08:31:35.000000000 +0200 +++ b/drivers/atm/iphase.c 2007-12-23 20:34:34.000000000 +0100 @@ -60,7 +60,8 @@ #include <asm/uaccess.h> #include <asm/string.h> #include <asm/byteorder.h> -#include <linux/vmalloc.h> +#include <linux/vmalloc.h> +#include <linux/jiffies.h> #include "iphase.h" #include "suni.h" #define swap(x) (((x & 0xff) << 8) | ((x & 0xff00) >> 8)) @@ -189,7 +190,7 @@ static u16 get_desc (IADEV *dev, struct int ltimeout; ia_hack_tcq (dev); - if(((jiffies - timer)>50)||((dev->ffL.tcq_rd==dev->host_tcq_wr))){ + if((time_after(jiffies,timer+50)) || ((dev->ffL.tcq_rd==dev->host_tcq_wr))) { timer = jiffies; i=0; while (i < dev->num_tx_desc) { @@ -1223,7 +1224,7 @@ static void rx_intr(struct atm_dev *dev) iadev->rx_tmp_jif = jiffies; iadev->rxing = 0; } - else if (((jiffies - iadev->rx_tmp_jif) > 50) && + else if ((time_after(jiffies, iadev->rx_tmp_jif + 50)) && ((iadev->rx_pkt_cnt - iadev->rx_tmp_cnt) == 0)) { for (i = 1; i <= iadev->num_rx_desc; i++) free_desc(dev, i); - To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
