Its 8029 and I see what the problem is. I'm looking into a fix.</p> <p>The logic of osp_lprocfs_init() needs review. If osc_proc_dir is an ERR_PTR() then it shouldn't be used later in the function. If lprocfs_add_symlink() then we shouldn't remove osc_proc_dir. There is no reason that I can tell for us to allocate a copy of name. If there is a reason to allocate it then it should be freed regardless of whether or not it has "osc" as a substring.</p> <p>In osp_init0() the proc cleanup should remove obd_proc_private.</p> <p>It's been reverted. Let me know if problems still exist.</p> <p>Nathaniel</p> <p>Could you please confirm whether the revert of the <a href="https://jira.whamcloud.com/browse/LU-3319" title="Adapt to 3.10 upstream kernel proc_dir_entry change" class="issue-link" data-issue-key="LU-3319"><del>LU-3319</del></a> patch - <a href="http://git.whamcloud.com/?p=fs/lustre-release.git;a=commit;h=b9b4614c1e302058ed9863b1ab73b7def2c5c924" class="external-link" target="_blank" rel="nofollow noopener">http://git.whamcloud.com/?p=fs/lustre-release.git;a=commit;h=b9b4614c1e302058ed9863b1ab73b7def2c5c924</a> - has indeed removed this problem?</p> <p>Thanks</p> <p>Peter</p> <p>Problem was fixed with the revert of commit a97e4898ad9e0b (<a href="http://review.whamcloud.com/8029" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8029</a>).
