Hopefully this isn't too blunt, but the EWG has the open source paradigm ass-backwards. Right now, OS distros (us and SuSE) do their own releases with their own QE testing. Upstream we have some people from different companies participating and contributing code, but with admittedly thin testing resources devoted to upcoming upstream kernels. We catch some things, but I've also see something slip through the cracks on mlx4 hardware in both of the last two upstream kernel releases. The EWG does its own integration and testing work for OFED. Finally, the UNH-IOL does an entirely different type of testing, but no fixes. If an end users wants to know if bug X is fixed, then it matters who found the bug because it is likely fixed in that group's product, but not necessarily in the other group's products. If a user needs both bug X and bug Y fixed, and they were fixed by different groups, then things are screwed. That's not how open source is supposed to work. That is not the best use of all of our time. First and foremost, we should all be concentrating on upstream, because that is the work that pays off for all of the people distributing this code. You say end users don't use upstream? Of course they do. No matter whether they use OFED or Red Hat or SuSE or something else, all of them start with upstream. Put the effort where you get the most payback. --=20 Doug Ledford GPG KeyID: 0E572FDD --EmS8eR4uR608rlaUbQVKNdD1SQxmMkl54 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 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJWChoTAAoJELgmozMOVy/dIUMP/jQw3PZwINkspIeR9OxoB1YD b1KAD+YNuOjd1gAQ6l5aamDxXbx3QNzuTZckLcHauq7GhqjEZuL6NLBYDlKZD9+H N4xFv5kHS7lWEQBCX/Nz5/ER+Vxn8WwLqPVau6Jk92Gx9lq7NdzbKqNYZtpvQoYv tF1cJQWdteYU+OVUHGl/LBAp0VIZd5pgOOoIV2p3E5gJmX7oeAi4GWo8DXzyn08c BTFaWA7MmDHeihVhGzIbn7cb8VyApktzeHMTclkfcMCd6T9BMFg899kDKVbYXcF8 zDJWIAHIMINf8/bw1neCH5tByHS78kunW8ZTlo0o/u/DBW1mCzz73JyQBScHaXGQ alW6yYoMfcbi2sGWUtSDCtBM3tTW2DI6CpZDYQYGS1OY+juzICTmEmekvdjfWi7z /oXUD7QXOEKU7k00STcNyqmOxoRjkqOUiwTqB9iD9UUhxP6FMtctftavU1K+r3ys QXzZLoRjlv7w1cfW7KDlSiSX96EtQT6KG644943xvEcRkS2jWc/rFVmJFV4F/Kn1 HR/lg27dHFTFztphDDI3ho+HN1/irMHKMQ2xyomAU7TFNFOuzlqgPb6+tBp1pc4c sXEd94m8NAWhleF+EEPBQtfJfudNMuuqDz95nRs0eOBHJ2fhKw90edhsKS1J+WRt +Tv6IMf3sqtaFu8Em239 =6EDY -----END PGP SIGNATURE----- --EmS8eR4uR608rlaUbQVKNdD1SQxmMkl54-- -- 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
