Bug Minor Resolved Won't Do Patrick Farrell Patrick Farrell Thu, 7 Feb 2019 17:12:23 +0000 Fri, 16 Aug 2019 19:45:01 +0000 Fri, 16 Aug 2019 19:45:01 +0000 0 3 <p>Will this cover the changes Neil did upstream?</p> <p>Dunno, what did Neil do upstream?  Can you shoot me a link or two?</p> <p><a href="https://patchwork.kernel.org/project/lustre-devel/list/?series=63793" class="external-link" target="_blank" rel="nofollow noopener">https://patchwork.kernel.org/project/lustre-devel/list/?series=63793</a></p> <p>Ah, no, it will not.  I wasn't aware of those.  This is rather different - It's more performance oriented, though there may be some other stuff.</p> <p>Are you planning to merge those in?</p> <p>Yes I can merge them in. The question is should I do it right away to prevent collisions with you?</p> <p>If you're ready, that would be great.  My first patch (which I didn't push yet because of a Gerrit issue, I'll push it soon) is like, a one liner, so it won't matter.  But I am contemplating some bigger changes.</p> <p>I think a different LU for Neil's stuff would be good though.</p> <p>Peter do you want a new ticket or should <a href="https://jira.whamcloud.com/browse/LU-4423" title="Tracking of patches from upstream kernel to Lustre client" class="issue-link" data-issue-key="LU-4423"><del>LU-4423</del></a> be reused?</p> <p>Peter isn't on this ticket, but looking at <a href="https://jira.whamcloud.com/browse/LU-4423" title="Tracking of patches from upstream kernel to Lustre client" class="issue-link" data-issue-key="LU-4423"><del>LU-4423</del></a>, I would say use that.  Forgot we had it.</p> <p>Also Li is work on similar improvements.</p> <p>The specific work intended for this ticket wound up not being of benefit, and there are several other tickets where related work was done, so no reason to leave this open.</p> Related LU-11775 Development Rank 1|i00b8f: Rank (Obsolete) 9223372036854775807 Severity
