Rather than making a new patch, the patches from that ticket should be cherry-picked to b2_12</p> <p>Hmm, it looks like those patches are already backported to b2_12... Do the same compile problems exist on master, or only b2_12? Typically we do not accept patches for only LTS branches until they have been landed for master first, so that we don't lose fixes going forward. </p> <p>Doh! Your patch <b>is</b> for master... For some reason I thought the patch was pushed against b2_12 only. Too early I guess. </p> <p>I was trying to understand why we didn't see these problems with <a href="https://jira.whamcloud.com/browse/LU-12705" title="build fails on power9 client" class="issue-link" data-issue-key="LU-12705"><del>LU-12705</del></a>, but it looks like these compile warnings are all in the server code, which we do not build/test on PPC.</p> <p>Olaf, are you trying to actually use PPC64le nodes for servers, or is this just because you are building both client+server packages normally and only the packages will only be used on the clients? We definitely haven't done much testing with large PAGE_SIZE on the server.</p> <blockquote><p>I was trying to understand why we didn't see these problems with <a href="https://jira.whamcloud.com/browse/LU-12705" title="build fails on power9 client" class="issue-link" data-issue-key="LU-12705"><del>LU-12705</del></a>, but it looks like these compile warnings are all in the server code, which we do not build/test on PPC.</p></blockquote> <p>That question has been bothering me, and I didn't connect the dots.
