Currently, there are lots of hard coding of 19 and -20 to represent maximum and minimum of nice value. This patch add three macros in prio.h for maximum, minimum and width of nice value. cc: Peter Zijlstra cc: Ingo Molnar Cc: Ingo Molnar Signed-off-by: Dongsheng Yang Signed-off-by: Peter Zijlstra Link: http://lkml.kernel.org/r/3994e89327b2b15f992277cdf9f409c516f87d1b.1392103744.git.yangds.fnst@cn.fujitsu.com Signed-off-by: Thomas Gleixner --- include/linux/sched/prio.h | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/include/linux/sched/prio.h b/include/linux/sched/prio.h index 1ceaaa1..c6974c4 100644 --- a/include/linux/sched/prio.h +++ b/include/linux/sched/prio.h @@ -1,6 +1,10 @@ #ifndef _SCHED_PRIO_H #define _SCHED_PRIO_H +#define MAX_NICE 19 +#define MIN_NICE -20 +#define NICE_WIDTH (MAX_NICE - MIN_NICE + 1) + /* * Priority of a process goes from 0..MAX_PRIO-1, valid RT * priority is 0..MAX_RT_PRIO-1, and SCHED_NORMAL/SCHED_BATCH
