The new kernel (3.10.0-493) introduces a lot of changes in the IB interfaces.

Lustre 2.8 support for RHEL7.3

Task Minor Closed Fixed Peter Jones Christopher Morrone RHEL7.3 llnl Tue, 30 Aug 2016 21:26:55 +0000 Thu, 16 Nov 2017 22:16:09 +0000 Thu, 16 Nov 2017 22:15:54 +0000 Lustre 2.8.0 1 7 <p>Chris</p> <p>When do you need this by?</p> <p>Peter</p> <p>The requirement for this is less specific. Within a few weeks. I already have it building locally. I am more concerned that this brings us up to 44 patches beyond b2_8_fe, and that is more patches than I would like to see us carrying locally.</p> <p>Yipes, that is a lot of newer kernel stuff being back ported. I didn't expect the work for newer kernels to become so important so quickly.</p> <p>Yes! RH backported an awful lot in this update. My suspicion is that our pressures to get Intel OPA support into the RHEL kernel may have triggered this big packport of rdma-related patches in the RHEL kernel. But I could be wrong.</p> <p>It took me longer than I expected to get the right patches in place for Lustre 2.8 to work, but it would have been quite a bit worse if I didn't have your new kernel work already in place on Lustre's master branch. So thanks for that work, James!</p> <p>Chris I started the work of the port to 2.8. I needed it for our Mellanox 3.3 systems as well. So far I have:</p> <p><a href="http://review.whamcloud.com/#/c/22944" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/22944</a><br/> <a href="http://review.whamcloud.com/#/c/22945" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/22945</a><br/> <a href="http://review.whamcloud.com/#/c/22946" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/22946</a><br/> <a href="http://review.whamcloud.com/#/c/22947" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/22947</a></p> <p>I have more but I like to push the above first.</p> <p>Finished the port, now just to land it.</p> <p>Thanks Team,</p> <p>For initiating the activity for linking Lustre 2.8.0 + Centos 6.7 + MLNX_OFED-3.3-1.0.4.0.</p> <p>Thanks <br/> Atul Yadav</p> <p>Hi Team,</p> <p>For your reference, the issue description is given below:-</p> <p>Note: checking out '2.8.0'.<br/> ..<br/> ...<br/> HEAD is now at ea79df5...
