Subject: [PATCH v3 0/3] sched: A few uclamp fixes and tweaks

Hi all,

This is the v3 of a series previously posted here:

  https://lore.kernel.org/r/20210610151306.1789549-1-qperret@google.com

The first two patches are fixes that probably make sense on their own.
The 3rd patch introduces a new RLIMIT for uclamp, which can be used to
prevent userspace tasks from messing with their own uclamp requests.

Thanks!
Quentin
