I have a buildroot set up for building 3.11.x into RPMs that would take a lot of work to change to 3.12. As this is a problem with 3.11 as well (as I don't run or provide 3.12 anywhere), I'd like to test the fix on 3.11. Eventually, it will need to be fixed in the 3.11 series as well. --=20 Steven Haigh Email: netwiz@crc.id.au Web: https://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299 --ChXOjnsWiQKmFCgHko00ME7WsvWKhGJXk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (MingW32) iQIcBAEBAgAGBQJSVKKOAAoJEEGvNdV6fTHc75kP/3P74Bo/BbxWfeigS+IbaQzb Lp1F7W+ksD11QOG343Gq5H7Mq/dp5FKvhxzpcz8xKrAaQrjtWAQxl/+J6K2QXh0u YE6n45wAjdf8Yar9s8X0XKM3hC9XBkSHf7KAkwnrPgPvcyR7yabObtjlRqXrBPbF vRkVKix/EheY5JgSgvfE9Nraj5aCCTLgxdI4SVUAeVroZkl4d2V6bWGKqTz8+YgS NpefoC+BXsGmQxvFsSDxMOI68llMkE6xwwknJIiIBeMyr4MlD7c1MBdI5HlVD/9q mAdJ452p8DBTG4ZBTCHJOlpe1H8Qy2ml69uqD/2Og44RUrV5ehtX3/7FkhmgkoDH UQcD0XmzwSq99bpCJdzmLd+mDYBsebQtodhm1/kltB/lcwqirqMvX2NLSKsW8/1p jD8Fkb0Mcf165WfKnxwjTsDVqdmTLToHC+qhuLWCo0APjrcBQ75qNo+j1id4+DKK kvAofab9qWhGZkhDIa7efy+sqBSucFU6lMnNHL8sOCIFQ+e2Fg5h8XZfQXS4zKZM AeKzNitdvBWpDji70wxvsMsG5oT2lCWZ9OkmMdwQQh/6UY0uMXLdwriX6BD7LMlC suHc+jyLKL9EZluXj+Xv54QZiJulyLnEpA01mCuj4WQKjsSXfcTU0s6g0aebzfqi dXzgIVNN8wFYbQLpXsbl =+v9v -----END PGP SIGNATURE----- --ChXOjnsWiQKmFCgHko00ME7WsvWKhGJXk-- --===============1250954874258406228== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel --===============1250954874258406228==--
