As nobody is answering I answer to myself.  So I learn the hard way that 
I need to carefully check ChangeLog of latest DRBD kernel module release 
before trying to build it.  Latest officially supported Linux kernel 
version for v9.1.x was and still is 5.15, so it was irrelevant to try 
and build it on 5.16.

At least it's mentioned in the 9.1.7 ChangeLog

  * following upstream changes to DRBD up to Linux 5.15 and updated compat

Otherwise one probably needs to figure out which Linux version is 
supported by other means, maybe by checking what kernel version latest 
supported RHEL and Ubuntu distributions have.
