From mboxrd@z Thu Jan 1 00:00:00 1970 From: Leo Liang Date: Mon, 19 Jul 2021 17:19:22 +0800 Subject: [LTP] [PATCH v4, 0/2] cgroup/cgroup_regression_test: Fix umount failure Message-ID: <20210719091918.GA360@atcfdc88> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it The test sequence mount -t cgroup -o mkdir / rmdir / umount mount -t cgroup -o would easily fail at the last mount with -EBUSY on certain platform. Adding a little delay between "rmdir" and "umount" could fix the problem, so use tst_umount API instead of umount in "rmdir, umount" sequence. Changes since v1 - Use "tst_umount" instead of "sync" as suggested - Make "tst_umount" work with argument that has terminating slash Changes since v2 - Filter out the trailing slash instead of using mountpoint command Changes since v3 - Filter out the trailing slash only in grep command - Add comment in the test script Leo Yu-Chi Liang (2): lib/tst_test.sh: Make tst_umount work with argument has trailing slash cgroup/cgroup_regression_test: Fix umount failure .../controllers/cgroup/cgroup_regression_test.sh | 10 +++++----- testcases/lib/tst_test.sh | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-) -- 2.17.0
