Thanks for the suggestion.
The kernel source I am looking at: 3.9.0-rc8, does not a accessible
definition of ROUND_UP, but roundup(x,y) is, and fits the bill. I am
thinking of using it instead, unless it breaks on some older kernel version
that we care about.
>From kernel.h:
/* The `const' in roundup() prevents gcc-3.3 from calling __divdi3 */
#define roundup(x, y) ( \
{ \
const typeof(y) __y = y; \
(((x) + (__y - 1)) / __y) * __y; \
}
