[lustre-discuss] Lustre client on RedHat 7.8

[Simon Guilbault]

Hi, you can try these patches and check their respective Jira entry:
git cherry-pick --strategy=recursive -X theirs
97823e65efd85bb2db325232584d65646be5644f # for centos 7.8 LU-13347
git cherry-pick --strategy=recursive -X theirs
851ba18ee0424a3a4bf27d54d0c1af20eaf04ed6 # for centos 7.8 LU-13347
git cherry-pick --strategy=recursive -X theirs
14a18654a64ae05a94a4394d53b030ce91357e9a # for centos 7.8 LU-12904

It seems 14a186 is directly what should fix your specific error, but the
other one seems to be required when I tried to build it.
