With this patch, it fix failure on centos7.9 and centos8.4. But > I can't find kernel commit for filename wipe feature and journal > checkpoint ioctl. Can you provide them in commit message? I guess filename wipe feature commit is [1]https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?h=dev&id=6c0912739699d8e4b6a87086401bf3ad3c59502d and journal checkpoint iocl commit is [2]https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?h=dev&id=339183dfb87ce94f8e14a0db48cae093516e194c Since the commit[1] is a feature and this case is desinged to test this feature, so skipping this test looks ok on non-supported kernel.
