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> Cc: "Yang, Bo" <Bo.Yang@xxxxxxx> Cc: James Bottomley <James.Bottomley@xxxxxxxxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/scsi/megaraid/megaraid_sas.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/scsi/megaraid/megaraid_sas.c~drivers-scsi-megaraid-use-div_round_up drivers/scsi/megaraid/megaraid_sas.c --- a/drivers/scsi/megaraid/megaraid_sas.c~drivers-scsi-megaraid-use-div_round_up +++ a/drivers/scsi/megaraid/megaraid_sas.c @@ -1718,7 +1718,7 @@ static int megasas_create_frame_pool(str * Calculated the number of 64byte frames required for SGL */ sgl_sz = sge_sz * instance->max_num_sge; - frame_count = (sgl_sz + MEGAMFI_FRAME_SIZE - 1) / MEGAMFI_FRAME_SIZE; + frame_count = DIV_ROUND_UP(sgl_sz, MEGAMFI_FRAME_SIZE); /* * We need one extra frame for the MFI command _ Patches currently in -mm which might be from julia@xxxxxxx are linux-next.patch drivers-isdn-capi-kcapic-adjust-error-handling-code-involving-capi_ctr_put.patch net-ieee80211-adjust-error-handling.patch drivers-atm-use-div_round_up.patch drivers-block-use-div_round_up.patch drivers-media-video-use-div_round_up.patch drivers-misc-use-div_round_up.patch drivers-net-wan-use-div_round_up.patch drivers-scsi-use-div_round_up.patch drivers-scsi-megaraid-use-div_round_up.patch drivers-net-xen-netfrontc-use-div_round_up.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
