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)
)
