| |
From: Julia Lawall <julia@diku.dk>
The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable.
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 x,__divisor; @@
- (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // </smpl>
