Remove OBD_IOC_GET_MNTOPT ioctl as it's only used to pass info between mdd and mdt

Bug Minor Resolved Fixed Henri Doreau Nathaniel Clark easy Thu, 14 Jul 2016 16:19:10 +0000 Mon, 2 Oct 2017 10:42:46 +0000 Mon, 2 Oct 2017 10:42:46 +0000 Lustre 2.11.0 0 4 <p>It appears that both <tt>OBD_IOC_GET_MNTOPT</tt> and <tt>mdd_maxeasize_get()</tt> should either be replaced by a single <tt>mdd_dtconf_get()</tt> method that returns struct dt_device_param to the caller, <b>or</b> GET_MNTOPT should be replaced by a new <tt>mdd_mntopt_get()</tt> method for consistency. In either case the <tt>OBD_IOC_GET_MNTOPT</tt> definition should be removed, though a stub should be left behind, like:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> <span class="code-comment">/* was OBD_IOC_GET_MNTOPT _IOW (<span class="code-quote">'f'</span>, 220, mntopt_t) until 2.9 */</span> </pre> </div></div> <p>BTW I realized that another ioctl had opcode 220... good time to remove it.</p> <p>Henri Doreau (henri.doreau@cea.fr) uploaded a new patch: <a href="https://review.whamcloud.com/28777" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/28777</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8400" title="Remove OBD_IOC_GET_MNTOPT ioctl as it&#39;s only used to pass info between mdd and mdt" class="issue-link" data-issue-key="LU-8400"><del>LU-8400</del></a> mdd: remove OBD_IOC_GET_MNTOPT<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 5f60a895cc976f8df9cdd7dc7883eb5b4bb60511</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/28777/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/28777/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8400" title="Remove OBD_IOC_GET_MNTOPT ioctl as it&#39;s only used to pass info between mdd and mdt" class="issue-link" data-issue-key="LU-8400"><del>LU-8400</del></a> mdd: remove OBD_IOC_GET_MNTOPT<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 20ffe2191c828d3e4922429f2a98584d4e41eb53</p> <p>Landed for 2.11</p> Related LU-8330 Development Rank 1|hzyhi7: Rank (Obsolete) 9223372036854775807 Severity
