The test sequence
mount -t cgroup -o <controllers> <path>
mkdir <path>/<dir>
rmdir <path>/<dir>
umount <path>
mount -t cgroup -o <controllers> <path>
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
