Bug Blocker Resolved Fixed WC Triage Jian Yu zfs Mon, 8 Dec 2014 08:14:51 +0000 Mon, 8 Dec 2014 18:29:41 +0000 Mon, 8 Dec 2014 18:29:41 +0000 Lustre 2.7.0 0 6 <p>Have pushed <a href="http://review.whamcloud.com/12990" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/12990</a> to revert the change, since the patch only appears to be a performance optimization and nothing will re-break if it is reverted.</p> <p>If the original patch is actually good, and the test is just broken because it isn't relevant for ZFS, then someone should push a patch to fix or disable the patch for ZFS. I'd question disabling the test, however, because it passed previously for ZFS so if it is claimed that this is not relevant for ZFS there needs to be a good reason behind it. </p> <p>Patch landed to Master.</p> Related LU-5998 Development Rank 1|hzx22f: Rank (Obsolete) 16729 Severity
