Since coreutils upstream v8.32~47 commit a99ab266110795ed94a9cb4d2765ddad9c4310da Author: Jeff Layton <jlayton@kernel.org> Date: Thu Sep 19 11:59:45 2019 -0400 ls: use statx instead of stat when available stat(1) starts to use statx(2) call. In some testcase, if file does not exist, this breaks golden output like this: -stat: cannot stat 'SCRATCH_MNT/xxx': No such file or directory +stat: cannot statx 'SCRATCH_MNT/xxx': No such file or directory Add this filter to fix it, and add this filter to testcases that need it.
