Subject: [PATCH 00/16 for-tip V2] A series patches about sched priority.

Hi all,
	This patchset is all about priority. 

1. Add two inline functions in prio.h named nice_to_rlimit and rlimit_to_nice.
   They are converting the value between nice value [-20, 19] and 
   rlimit style value [1, 40].
2. Add a macro in ioprio.h named NICE_TO_IOPRIO.
   It convert nice value [-20, 19] to io priority [0, 7].
3. Others are all about replace hardcoding value about nice to MIN_NICE or MAX_NICE.

Changelog:
	-v1:
	  *Implement nice_to_rlimit and rlimit_to_nice with inline functions
	   rather than macro.
	  *Add a patch[16/16] to replace opened code implement with nice_to_rlimit().

Dongsheng Yang (15):
  sched/prio: Add a inline function named nice_to_rlimit() in prio.h.
  workqueue: Replace hardcoding of -20 with MIN_NICE.
  locktorture: Replace hardcoding of 19 with MAX_NICE.
  tools/mq_perf_tests: Replace hardcoding of -20 with MIN_NICE.
  mm: Replace hardcoding of 19 with MAX_NICE.
  ioprio: Add a macro named NICE_TO_IOPRIO.
  fs/hearbeat: Replace hardcoding of -20 with MIN_NICE.
  driver/block: Replace hardcoding of -20 with MIN_NICE.
  driver/char: Replace hardcoding of 19 with MAX_NICE.
  drivers/s390: Replace hardcoding of 19 with MAX_NICE.
  sched/prio: Add an inline function named rlimit_to_nice in prio.h.
  driver/staging/android: Use rlimit_to_nice to replace opened code
    implementation.
  driver/staging/lustre: Replace hardcoding of -20 with MIN_NICE.
  driver/scsi: Replace hardcoding of -20 with MIN_NICE.
  sched: Get rid of opened code implementation of funtion
    nice_to_rlimit().

Joe Perches (1):
  kernel/sys: Replace opened code implementation with nice_to_rlimit().
