Hi there
Am I correct in thinking that you are trying to build against IEEL rather than a community version of Lustre? It appears as such so I have moved this issue to the DDN project.

Hi, Peter
The problem has been reported here:
https://jira.hpdd.intel.com/browse/DDN-153
I open a new ticket LU-xxxx just because the problem is a general problem also existed on master, so i open a general ticket.

Ah ok. Then please can you correct the environment to be more accurate? Presently it says lustre-2.5.24
Thanks
Peter
Peter
Sorry for confusing!
The environment is:
lustre-2.7.51
Ubuntu 12.04
Kernel Version: kernel 3.2.68
I can't change the issue, could you help me?
Thanks
ok done 
Thanks, peter!
Bob
Can you please take care of this patch?
Thanks
Peter
Since I have a test cluster running Ubuntu 14 I also have run into this issue. I found a bug in the current patch. Also for Ubuntu 14 more patches will be needed to make this work. I will push those additional patches under this ticket.
Linking to the upstream work since Ubuntu back ported patches from 3.18 kernels.

I ran into the same problem with Debian Wheezy 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux and Lustre 2.5.3.90
Is there already a patch for this problem? I did a quick hack:

To enable support for Ubuntu 14 you need the two patches posted here;
http://review.whamcloud.com/#/c/14060
http://review.whamcloud.com/#/c/14507
I have tested the patches on Ubuntu 14 and on RHEL6.5. The autoconf had to be reworked since I found Lustre was compiling incorrectly thus I ended up with broken clients.
This by default will over Debian Wheezy support as well.
Thomas, there is already a fix in flight for the d_child problem. Please see LU-6426; http://review.whamcloud.com/#/c/14060
Ok, perfekt. I will try these patches on Wheezy + Lustre 2.5.3.90.
Many thanks, Thomas
I updated to the patch to handle the debian Wheezy 3.2 kernels now. I have tested the latest patch on:
RHEL6.5
RHEL7.1
debian Wheezy/Jesse running a 3.2 kernel
Ubuntu 14.04 - linux-headers-3.11-32-generic
linux-headers-3.11-39-generic (yes d_alias changed between each ubuntu kernel)
SLES11 SP3
Linux 4.0 kernel
Each of those cases correctly compiled lustre.
