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)

)
