Ah, sorry about that, try this tree again: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/queue.git That patch was dropped for favor of a patch that Matthew Vick put together (and recently got pushed upstream). So my queue no longer has that patch in the queue, since it got dropped. --=-jfimw7ZWYwk+l2Yg+stM Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCgAGBQJU2G3eAAoJEOVv75VaS+3OLQUP/2xZ8T5jGOHbBK+vwHbBYkOQ NAKX2zPIsiJnzOQ02i3RqcgKsSGhsrDjVuEVSUmSWj5JeIsxwCpm4X85JFcTtbLR rHdkzUY+s3+O3mAtmCGLuCoIX+MDCAzGRbpuSJz6RzUvNE6HbM140cBEkTQX76UH WcjQAQFP4QYOW0M6dnimkBn1h0wpLCwU1PloNsP40Oj8R08Yw481sxZ1CUhtX7ca YYgWZJSmcwpm7+6+iEBtf/QvKApS6NoYOW8FsNX35fr767AyncDj7a2Fqk/7AbrO JX9ipW2ReB9hrl56a3GN/a0+apANNUtIGohvDFVlzblfS7TYgjW3R+5leDIcb9lB +kS5Vfx0U073rs5rpyi2GJduinImOgkk1wuBTdBK6owaLz9Z8VR0nzaK703/C85d QkxfHBTUMLhVQgEs/K/VgQDQaD/wfHMJFL9+O/s46YA6VInp+XAmGheiJGrPqjuV mVszwsOAAmtMhY14eKvThcDL9pwojSiF3LAtNB89Ya2Fd1BCi6FOsUPnnNVC4tRs x5ZRsghsgeebBwAoMAH0Xqvbb1/YSeSqow3Yi/TSyojrUrNMU1ZyDESrcn9Ol+dD j0TQSSMj4VcuRhEe834uv2CwgVUOYj+TkdIep7+E6f5QbUgU08xnpRcHkeqEU0sB /xFnVMMgb4qvkMiQ1y0i =Y+xH -----END PGP SIGNATURE----- --=-jfimw7ZWYwk+l2Yg+stM--
