On my Fedora Rawhide, I observer following test failure:

  1) Error:
TestFileExhaustive#test_birthtime:

The behavior of statx(2) depends on the filesystem

birthtime may not be supported on some filesystems, and
NotImplementedError can be raised. [Bug #15972]

I just wonder what FS are supported actually. I am using Ext4, which is not an esoteric FS IMO and this works:
