From: Julia Lawall <julia@xxxxxxx> The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @haskernel@ @@ #include <linux/kernel.h> @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/net/wan/sbni.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -u -p a/drivers/net/wan/sbni.c b/drivers/net/wan/sbni.c --- a/drivers/net/wan/sbni.c +++ b/drivers/net/wan/sbni.c @@ -856,7 +856,7 @@ prepare_to_send( struct sk_buff *skb, len = SBNI_MIN_LEN; nl->tx_buf_p = skb; - nl->tx_frameno = (len + nl->maxframe - 1) / nl->maxframe; + nl->tx_frameno = DIV_ROUND_UP(len, nl->maxframe); nl->framelen = len < nl->maxframe ? len : nl->maxframe; outb( inb( dev->base_addr + CSR0 ) | TR_REQ, dev->base_addr + CSR0 ); -- 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
