Subject: [PATCH v4 0/6] selftests/resctrl: Add resctrl_tests into kselftest set

Hello,

The aim of this series is to make resctrl_tests run by using
kselftest framework.
- I modify resctrl_test Makefile and kselftest Makefile,
  to enable build/run resctrl_tests by using kselftest framework.
  Of course, users can also build/run resctrl_tests without
  using framework as before.
- I change the default limited time for resctrl_tests to 120 seconds, to
  ensure the resctrl_tests finish in limited time on different environments.
- When resctrl file system is not supported by environment or
  resctrl_tests is not run as root, return skip code of kselftest framework.
- If resctrl_tests does not finish in limited time, terminate it as
  same as executing ctrl+c that kills parent process and child process.

Difference from v3:
- I reodered all patches of this patch series.
- I updated the print message of ksft_exit_skip() to give more information. [PATCH v4 3/6]
- I simplified tools/testing/selftests/resctrl/Makefile to use kselftest's lib.mk. [PATCH v4 4/6]
- I improved README of resctrl_tests. [PATCH v4 5/6]
- I moved license patch to this patch series. [PATCH v4 6/6]
https://lore.kernel.org/lkml/20220216022641.2998318-1-tan.shaopeng@jp.fujitsu.com/ [PATCH V3]

This patch series is based on v5.16.

Thanks,
