Firstly, we generally use 'larger' headers first, i.e. sched.h, mm.h, etc.

Secondly, this:

#include <linux/sched.h>
#include <linux/cpumask.h>
#include <linux/cpuset.h>
#include <linux/mutex.h>
#include <linux/sysctl.h>
#include <linux/nodemask.h>

... can probably be further reduced, because for example sched.h already includes
some of these headers.

I.e. instead of a mindless single liner that helps no-one, try to improve the code
for real...

Thanks,

Ingo
