[DRBD-user] building v9

[Pierre-Philipp Braun]

Hello

I am having troubles building the v9 module although I tried with various releases and against many kernel versions.

With branch drbd-9.0 and drbd-9.0.26-0rc2 against stock Ubuntu 5.8.0-31-generic

In file included from /root/tp/drbd/drbd/drbd_main.c:19:
./include/linux/vermagic.h:6:2: error: #error "This header can be included from kernel/module.c or *.mod.c only"
    6 | #error "This header can be included from kernel/module.c or *.mod.c only"
      |  ^~~~~

With release drbd-9.0.25-2 against stock Ubuntu 5.8.0-31-generic

What am I missing?  That's really hard to built and assistance would be much appreciated.

PS: Coccinelle is only needed for backwards compatibility, right?  Is there a way to avoid its usage while using a recent enough kernel?

Thanks
