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.

[Thomas Stibor]

Ok, perfekt. I will try these patches on Wheezy + Lustre 2.5.3.90.
Many thanks, Thomas

Thomas, there is already a fix in flight for the d_child problem. Please see LU-6426; http://review.whamcloud.com/#/c/14060
