Check for cpu_map__dummy_new() or cpu_map__new() to be called in
perf_evlist__create_maps() is more complicated. This patch moves

Convert 20 - task_nice(p) to nice_to_rlimit(task_nice(p)).
Reduce the indent the switch case labels while there.

Peter,
Sorry for the noise, I should add this patch into my thread 'A
series patchse about sched priority', as some patch depends on this
patch. Otherwise, there
will be a conflict.
Thanx.,

There is a macro rlimit_to_nice in linux/sched/prio.h to convert priority in
rlimit
to nice value.
This patch replace the opened implementation with rlimit_to_nice.

Applied to wq/for-3.15
, please take a look at the other patches
in this thread. Thank you.
Dongsheng Yang (3):
tracing: Use inline task_nice() to get rid of an open coded
implementation of it.
sched/prio: Replace hardcoding of 40 with NICE_WIDTH.
sched: Use clamp() and clamp_val() to make it more readable

This patch move the implementation to a macro NICE_TO_IOPRIO, making
1 - 100 of 733 matches
