Subject: [PATCH v3 5/5] selftests/resctrl: Remove duplicate codes that clear each test result file
Date:   Tue,  1 Nov 2022 18:43:41 +0900
Message-Id: <20221101094341.3383073-6-tan.shaopeng@jp.fujitsu.com>
In-Reply-To: <20221101094341.3383073-1-tan.shaopeng@jp.fujitsu.com>

Precedence: bulk

Before exiting each test function(run_cmt/cat/mbm/mba_test()),
test results("ok","not ok") are printed by ksft_test_result() and then
temporary result files are cleaned by function
cmt/cat/mbm/mba_test_cleanup().
However, before running ksft_test_result(),
function cmt/cat/mbm/mba_test_cleanup()
has been run in each test function as follows:
  cmt_resctrl_val()
  cat_perf_miss_val()
  mba_schemata_change()
  mbm_bw_change()

Remove duplicate codes that clear each test result file.
