The short answer is that it will likely work but has not been formally tested.

Subject: [lustre-discuss] Kernel/OS/Lustre version matching
Hi all, I hope I haven't missed something obvious in the docs here but I am confused about versions.
I'm trying to install the lustre client on a Centos 8.2 system with the 4.18.0-193 kernel, which is an un-updated kernel.
The client install instructions at  say to look at the changelog  for the list of supported kernels. There, that kernel is only listed against the unreleased 2.14.0 version. However the Lustre Support Matrix at  shows RHEL 8.2 as a client using 2.12.5. Does that mean 2.12.5 will work with the above kernel, or should I use another kernel with that OS version? If the former, how come it's not listed in the changelog?
On a related note the changelong only shows 2.x.0 versions - is kernel compatibility the same for all 2.x.y versions for the same x?
many thanks for any help
Please note I work Tuesday to Friday.
