I can't compile... I using Slackware 8.0, kernel 2.2.19, no SMP, and
modified Makefile.var (KAF_i386 := -fno-strict-aliasing
#-mpreferred-stack-boundary=2), but it returns

There is a typefault in drbd_receiver.c

In line 630 it must be NR_REQUEST instead of NR_REQUESTS

Patching the kernel means that you have to modify the ksyms.c in your kernel
source tree to export the symbol 'wake_up_process'. Otherwise the module
will not load because of unresolved externals.

You must also export 'pidhash'

EXPORT_SYMBOL(pidhash);
EXPORT_SYMBOL(wake_up_process);

I also had to make the following changes to DRBD:

Makefile.vars: removed -mpreferred-stack-boundry=2

drbd/Makefile: defined REQ_O as "drbd-req_2.2.0"

moved init_MUTEX_LOCKED, init_MUTEX, init_waitqueue_head and struct
wait_queue from drbd_main.c to drbd_int.h

drbd/drbd_main.c: changed list_add_tail to list_add
