[DRBD-user] drbd-9.0.25-1 doesn't build against linux 5.8

[Adam Goryachev]

I didn't see any response to this on the archives, and am having the 
same problem. I'm trying to install onto a raspberry pi 4 using ubuntu 
20.10.

The last part of my compile log:

   CC [M]

Is there a simple solution to this?
