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: -v2: *Splite [2/16] into two patches, one is about the whitespace changes, and the other is about nice_to_rlimit(). -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 (16): sched/prio: Add a inline function named nice_to_rlimit() in prio.h. kernel/sys: Replace opened code implementation with nice_to_rlimit(). 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().
