Okay, cool.  I'll take it into consideration when I write the kernel 
patcher.

Wow.  I have no idea at all.  I swear I needed this to build monolithic.
digging...   oh, I see.  This was an early attempt to solve the problem, 
but I later solved it in drbd_main.c differently.  Looks like this 
statement had no effect on my build.

however, for completeness, it should be as you suggest:

Which leaves it up to the kernel headers to define that interface when 
building monolithic.

Thanks for putting up with my messy patches!  :)
