Bug Minor Resolved Fixed WC Triage Dmitry Eremin kw Wed, 5 Nov 2014 16:52:50 +0000 Wed, 30 Aug 2023 21:36:50 +0000 Thu, 11 Dec 2014 18:41:06 +0000 Lustre 2.7.0 0 6 <p>This code was added in the "<a href="https://jira.whamcloud.com/browse/LU-3613" title="Get parent_fid + name for an entry" class="issue-link" data-issue-key="LU-3613"><del>LU-3613</del></a> llite: Add ioctl to get parent fids from link EA" patch. Thomas or Henri, could you please provide a patch?</p> <p>There's already a patch aiming at cleaning up this code (for other reasons). It is tracked as <a href="https://jira.whamcloud.com/browse/LU-5837" title="ll_getparent improvements" class="issue-link" data-issue-key="LU-5837"><del>LU-5837</del></a> and is currently being reviewed at <a href="http://review.whamcloud.com/#/c/12527/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/12527/</a>. The reported pattern has been replaced by something cleaner.</p> <p>This said, it looks like a false positive to me. Provided ldata is consistent, the idx/linkno checks should prevent from using ln uninitialized.</p> <p>Patch landed to Master.</p> Related LU-4629 LU-5837 Development Rank 1|hzx0an: Rank (Obsolete) 16420 Severity
