While it is backported to RHEL6 2.6.32 kernels, it does not exist for vanilla kernels before that point.</p> <p>The patch from <a href="http://review.whamcloud.com/5700" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5700</a> "<a href="https://jira.whamcloud.com/browse/LU-1778" title="Root Squash is not always properly enforced" class="issue-link" data-issue-key="LU-1778"><del>LU-1778</del></a> llite: fix inconsistencies of root squash feature" added uses of kstrtoul() to Lustre that break the build for older kernels. While it would be possible to convert those calls over to simple_strtoul() that function is deprecated in newer kernels, and checkpatch.pl will generate a warning, so using kstrtoul() is the right thing for newer kernels.</p> LU-6266
