The patch titled drivers/block: Use DIV_ROUND_UP has been removed from the -mm tree. Its filename was drivers-block-use-div_round_up.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/block: Use DIV_ROUND_UP 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> Cc: Jens Axboe <jens.axboe@xxxxxxxxxx> Cc: <mike.miller@xxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/block/cciss.c | 8 ++++---- drivers/block/cpqarray.c | 2 +- drivers/block/floppy.c | 8 ++++---- 3 files changed, 9 insertions(+), 9 deletions(-) diff -puN drivers/block/cciss.c~drivers-block-use-div_round_up drivers/block/cciss.c --- a/drivers/block/cciss.c~drivers-block-use-div_round_up +++ a/drivers/block/cciss.c @@ -3460,8 +3460,8 @@ static int __devinit cciss_init_one(stru hba[i]->intr[SIMPLE_MODE_INT], dac ?
