[PATCH v2 0/3] A few uclamp fixes

[Quentin Perret]

Hi all,

This series groups together the v2 of a few patches I orignally sent
independently from each others:

  https://lore.kernel.org/r/20210609143339.1194238-1-qperret@xxxxxxxxxx
  https://lore.kernel.org/r/20210609170132.1386495-1-qperret@xxxxxxxxxx
  https://lore.kernel.org/r/20210609175901.1423553-1-qperret@xxxxxxxxxx

But since they're all touching uclamp-related things, I figured I might
as well group them in a series.

The first one is a pure fix, and the two others change a bit the
sched_setattr behaviour for uclamp to make it more convenient to use,
and allow to put restrictions on the per-task API.

Changes since v1:
 - fixed the CAP_SYS_NICE check to handle the uclamp_{min,max} = -1
   cases correctly;
 - fixed commit message of UCLAMP_FLAG_IDLE patch.

Thanks,
Quentin

  sched: Fix UCLAMP_FLAG_IDLE setting
  sched: Skip priority checks with SCHED_FLAG_KEEP_PARAMS
  sched: Make uclamp changes depend on CAP_SYS_NICE
