Otherwise, it is very difficult to make any assessment of how often "whatever this problem is" is hit, and what the consequences of hitting it are.</p> <p>Is it easily hit with a specific workload, does it cause a crash, does it cause data inconsistency or loss, or only an occasional problem that is seen under a specific workload, or just a build problem on a certain kernel or GCC?</p> <p>This was noted during a code review. I do not have a test that causes this condition to fault.</p> <p>Thanks for the update. This makes it easier to understand the impact of the bug and eg. whether it is important to backport to 2.12 or not.</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/39797/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/39797/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13940" title="it_lock_bits should be bit-wise tested" class="issue-link" data-issue-key="LU-13940"><del>LU-13940</del></a> llite: it_lock_bits should be bit-wise tested<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 86868afde5a5ebfda9aa8560a464c046d97d14d6</p> <p>Landed for 2.14</p> Development Rank 1|i018uv: Rank (Obsolete) 9223372036854775807 Severity
