https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-273 Lustre <p>When building the patched kernel with lustre 2.0.59.0 and above, error happens that "sched_show_task undecleared here". I check the patches in rhel5.series and find that the symbol sched_show_task has been exported in export-show_task-2.6.18-vanilla.patch in sched.c but not defined and decleared in any other place. So I think the symbol name may be wrong and in the wrong place. After changed to EXPORT_SYMBOL(show_task) and put it in line 5055, everything looks ok.</p> rhel 5u6, kernel, 2.6.18-164.11.1, lustre 2.0.59.0 and above LU-273

the patch export-show_task-2.6.18-vanilla.patch of rhel5 has some issues in lustre 2.0.59.0 and above

Bug Minor Resolved Fixed Zhenyu Xu Larry Gu Wed, 4 May 2011 02:09:15 +0000 Wed, 18 May 2011 23:13:03 +0000 Wed, 18 May 2011 22:07:11 +0000 Lustre 2.1.0 Lustre 2.1.0 0 0 <p>Indeed, i can reproduce the same problem with linux-2.6.18-194.17.1.0.1:</p> <p>$ grep sched_show_task kernel/sched.c<br/> EXPORT_SYMBOL(sched_show_task);<br/> void sched_show_task(struct task_struct *p)<br/> sched_show_task(p);</p> <p>It seems that patch is confused.</p> <p>It looks like Bobijam is working on this</p> <p>patch tracking at <a href="http://review.whamcloud.com/493" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/493</a></p> <p>In newer kernels it is using dump_trace() to Handle this functionality. Is the RHEL5.6 kernel having that function? That woul allow us to drop this patch emtirely.</p> <p>It is odd that sched_show_task() function in exported, but libcfs/libcfs/linux/linux-debug.c it is still using show_task(). Is that correct? I don't have this kernel to check. </p> <p>rhel5u6 kernel also has dump_trace(). By the way, I check the patch by Bobijam, find he change the function name, not the symbol name exported. As Andreas said, libcfs/libcfs/linux/linux-debug.c also called show_task(). So I have a question that, which way is useful?</p> <p>it looks that since 2.6.18 kernel, we always use dump_trace, that explains linux-debug.c calls show_task() while we export sched_show_task() and nothing happened. I think we can drop this kernel patch entirely.</p> <p>Integrated in <span class="image-wrap" style=""><img src="http://newbuild.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black"
