New Revision: 194887
URL: http://svn.freebsd.org/changeset/base/194887

Log:
  - Invert the flag to indicate if VOP_GETATTR was successful rather than
    unsuccessful, as an old kernel will have the padding zero'ed. Doing it this
    way makes it possible for userland tools checking the flag to work correctly
    on older kernels.
