Subject: [PATCH v4 5/5] selftests/resctrl: Remove duplicate codes that clear each test result file
Date: Thu, 17 Nov 2022 10:05:41 +0900 [thread overview]
Message-ID: <20221117010541.1014481-6-tan.shaopeng@jp.fujitsu.com> (raw)
In-Reply-To: <20221117010541.1014481-1-tan.shaopeng@jp.fujitsu.com>
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,
while ensuring cleanup properly even when errors occur in each test.
