For the commit mentioned in the test case:
 * The problem has been fixed by commit:
 * 764baba80168 "ovl: hash non-dir by lower inode for fsnotify"

In commit 764baba80168, it stated that:
    The issue dates back to initial version of overlayfs, but this
    patch depends on ovl_inode code that was introduced in kernel v4.13.

So it would probably not suitable for X.

Our Xenial 4.4 kernel doesn't have the ovl_inode code, so blacklist this
testcase for kernels older than 4.13.
