I've added a test to xfstests that exercises the new statx syscall.  However,
it fails on btrfs:

     Test statx on a directory
    +[!] stx_nlink differs, 1 != 2
    +Failed
    +stat_test failed

because a new directory it creates has an nlink of 1, not 2.  Is this a case
of my making an incorrect assumption or is it an fs bug?

David
