The list primitive hlist_add_after() is gone. A similar but not identical new primitive hlist_add_behind() exists instead. We will probably need some autoconf support to adapt to the difference. I note that in the upstream lustre client code in the 3.17 staging drivers sources instances of using hlist_add_after() have been replaced with hlist_add_behind().</p> fc21/fc22 LU-5609

Some tcp socket changes in libcfs. Also the directIO api has changed which impacts llite. I was looking at it before but have been busy working on other parts of the code (<a href="https://jira.whamcloud.com/browse/LU-5275" title="clean up technical debt for proc_dir_entry changes" class="issue-link" data-issue-key="LU-5275"><del>LU-5275</del></a> and <a href="https://jira.whamcloud.com/browse/LU-3963" title="cleanup libcfs wrappers" class="issue-link" data-issue-key="LU-3963"><del>LU-3963</del></a>).</p> <p>We should link this to <a href="https://jira.whamcloud.com/browse/LU-4416" title="support for 3.12 linux kernel" class="issue-link" data-issue-key="LU-4416"><del>LU-4416</del></a>.</p> <p>Thomas Stibor (t.stibor@gsi.de) uploaded a new patch: <a href="http://review.whamcloud.com/14661" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/14661</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-5609" title="support for 3.17 kernel" class="issue-link" data-issue-key="LU-5609"><del>LU-5609</del></a> libcfs: renamed hlist_add_after to hlist_add_behind<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 08c04de1e6309627ee5a6dbb68553dccc7f6dd3f</p> <p>I provided a simple patch <a href="http://review.whamcloud.com/#/c/14661/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14661/</a><br/> for providing compatibility of renamed hlist_add_after to hlist_add_behind</p> <p>I have the hlist support completed with patch <a href="http://review.whamcloud.com/#/c/14624" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14624</a>. Sorry I didn't include on the review. Will change that. Are you testing with newer kernels? If that is the case I have many more patches coming.</p> <p>Hi James,<br/> I haven't seen that you already are working on a bunch of patches. I will abandon the patch.<br/> Yes, I started testing/patching with Debian Jessie Kernel 3.16.7-ckt9-3~deb8u1, and would be happy<br/> to test your patches. We are currently setting up a new cluster with Jessie client which will talk<br/> to Debian Wheezy 3.2 SPL/ZFS OSS/MDS servers.</p> <p>Cheers<br/> Thomas</p> <p>I'm currently working on Ubuntu 15 (3.19 kernel) support. Also I'm testing against greg's upstream staging tree. I will include you in those patches as well.</p> <p>Now that Ubuntu15 support is complete we support kernels up to 3.19. This ticket can be closed.</p> <p>Last patch that landed for <a href="https://jira.whamcloud.com/browse/LU-6215" title="Sync Lustre external tree with lustre linux kernel client" class="issue-link" data-issue-key="LU-6215"><del>LU-6215</del></a> brought lustre client support up to 4.1.
