I don't know.  That sounds like something you should look up in
CentOS/RHEL/Fedora documentation.

Or you maybe you can just skip the custom kernel altogether.  That is
largly what I do.  I haven't built a kernel myself in years, actually.
When LU-684's patch lands, Lustre-owned custom kernels can be a thing of
the past for everyone!

Get on the bandwagon early and stop using Lustre-patched kernels now. :)
