Yeah. Linus, as you can see from the story quoted above, I'm busy rebuilding my primary workstation after frying four SSDs (doh!). I've reviewed the patch Leon is referencing here and I'm fine if he sends it to you, or you can wait about a day or so and I can get it to you (reinstall is done, now working on the restoring of backups, should be mostly normal by sometime tomorrow). --=20 Doug Ledford GPG KeyID: B826A3330E572FDD Key fingerprint =3D AE6B 1BDA 122B 23B4 265B 1274 B826 A333 0E57 2FD= D --GF5QTfGIRFIIbI4AfXXjmxG0BIGpmvCtd-- --hNRr060aE5snGiexomfSPHEBq6Fj536EK Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJZ+LPcAAoJELgmozMOVy/dc7UP/0U4sBaLJn7WYmXDwBlxT4c5 JEwIyzp4YB52Au+rjzY/l/EiZ/gRpo1RiVMUvhgbW9Sk8vye63tG/F+unz75pDzO JGmt+C9xFpTzDJADEpju/sARAZMThwkaKxWmH4sLy4Se9eaY3ibq5slIE+kZ+hCV sjUkn9m5yP7JLGQulJ6FKzCEB0dBVcvf59ER1mSNIbmPPG3Ue/JUBGSrFbsHKNhH tIeHl7MHNB4TtAX0Fut3nO8MbqM78lPjd9mFlkfnTiDxaB6/CN+RuyeV5cS1igW8 g22DMbe/mZAcR8yRpp9ZJbbJ9YLtbGxrwlS4AN8wMVmqnq+7BZ7vcYYXvwCeqVs8 45lusNIW6lsXFaiiJtqv2ZmR2sxgCLp+M6cU0AFnZiUM23phVoES+YhrrN5n3blW B8uDIThbQh+4Q+xjvi7W8tCzA7ma7rlNt7MCyPb9hoS0W/GO0gU5guEuCbW5fJST s0RSu4ryh0h65IksYTiiUMjH2UB4UKdOIrs+PCvemCAzbe2hewpLkoKBxuKlaIgU atEetb8qSRIphgY8I02ZVIWWibaB6dbtqybP9Yo/tblzhcQQkPiA4TjAideaLpy0 0yVubesCLD7SKJ2qiZ9JUwUQVgL+kzmQ07GksVk2n5GSsf/ostn027wn/OQGiwXi eT3ZjEc55OVeQ+Y1BaoV =6zEg -----END PGP SIGNATURE----- --hNRr060aE5snGiexomfSPHEBq6Fj536EK-- -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
