However, I don't think you should need patch <a href="https://review.whamcloud.com/28924" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/28924</a>. Less patch means less problem. Please let me know if you want any or both of them.</p> <p>Hi Jinshan, thank you.</p> <p>I would like all three patches.  Re: 28924, I want to preserve the ability of the other sites to upgrade to ZFS 0.7.0 and then roll back if they find they need to, even though that is unlikely.</p> <p>All the relevant mods have landed to b2_8_fe:</p> <p><a href="https://review.whamcloud.com/29596" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/29596</a><br/> <a href="https://review.whamcloud.com/29639" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/29639</a><br/> <a href="https://review.whamcloud.com/29640" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/29640</a></p> Related Development Rank 1|hzzlqv: Rank (Obsolete) 9223372036854775807 Severity
