[Drbd-dev] Get drbd-9.0 branch building with Linux 5.9 and 5.10

[Christoph Böhmwalder]

Hi Michael,

Thanks for this great contribution!

Unfortunately, we duplicated some work here, but neither of us could 
have known that :)
Over the last few days I fabricated some patches that fix some of the 
same problems, ultimately leading to the same result.

I'll review your patches – on first glance it seems like some of your 
approaches may actually be better than mine. If the patches are exactly 
the same, I'll attribute you since you published your patches first. 
I'll mix and match with my patches, since they are more thorough in some 
places (for example, I did go to the trouble of creating a compat test 
for sched_setscheduler()).

Some of these patches are still under internal review, so this may take 
some time, but I'll let you know which of yours I chose.

Thanks again!
