Error in building openafs on ubuntu 22.04

Respected sir/madam,
I tried building the source code of openafs from the git repo and also
downloaded the latest stable release of openafs. I am using ubuntu 22.04
and kernel version is 6.8.0-52-generic.
 But I run into a number of errors everytime which I keep trying to
resolve.
I want to ask a few doubts just so that I know I am not doing anything
wrong.

1) the release note for the latest stable release says that support has
been added for kernel 6.13. But does that mean it no longer supports older
kernels? Should I download an older stable release based on .my kernel
version?

2) is it recommended that I downgrade my kernel and try an older kernel?

3) I first tried installing openafs via apt package manager But i found out
that it older openafs version which does not support latest kernel modules.

Kindly advise.
Thank you
Satyarth Singh
