Patch 33968 has been replaced by <a href="https://review.whamcloud.com/#/c/34392" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/#/c/34392</a>.</p> <p>That is for building. I suspect you will need the patch from <a href="https://jira.whamcloud.com/browse/LU-12137" title="update client to use iterate_shared" class="issue-link" data-issue-key="LU-12137"><del>LU-12137</del></a> as well since I saw mounting issues with 4.14 kernels. Luste has improper locking in osd-ldiskfs.</p> <p>When it comes to testing I suspect the ARM test we see disabled in testing also be an issue for RHEL8. Lastly the "lustre/.fid" handling no longer works properly with newer kernels.

For server support, the following patches are needed to be back-ported:<br/> <a href="https://jira.whamcloud.com/browse/LU-12269" title="Support RHEL 8.0" class="issue-link" data-issue-key="LU-12269"><del>LU-12269</del></a> <a href="https://review.whamcloud.com/35665" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35665</a><br/> <a href="https://jira.whamcloud.com/browse/LU-11838" title="Support linux kernel version 4.18" class="issue-link" data-issue-key="LU-11838"><del>LU-11838</del></a> <a href="https://review.whamcloud.com/34674" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34674</a><br/> <a href="https://jira.whamcloud.com/browse/LU-11838" title="Support linux kernel version 4.18" class="issue-link" data-issue-key="LU-11838"><del>LU-11838</del></a> <a href="https://review.whamcloud.com/34689" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34689</a><br/> <a href="https://jira.whamcloud.com/browse/LU-12625" title="sometimes configure can't detect timespec64 with gcc8" class="issue-link" data-issue-key="LU-12625"><del>LU-12625</del></a> <a href="https://review.whamcloud.com/35675" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35675</a><br/> <a href="https://jira.whamcloud.com/browse/LU-12652" title="osd_attr_set() fails with ENOSPC on linux-4.18" class="issue-link" data-issue-key="LU-12652"><del>LU-12652</del></a> <a href="https://review.whamcloud.com/35750" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35750</a></p> <p>Hi Jian,</p> <p>I think that list is missing a patch for 8.1 support (with the latest 8.1 kernel).
