The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /(d)) but is perhaps more readable. The Coccinelle script used to make this change is as follows: @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) ) Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Reviewed-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
