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)
