Erro compilando DRBD em Slack 12.2 Kernel 2.6.30.5

Pessoal, bom dia.

Estou com um problema para compilar o DRBD dentro do kernel, já fiz isto uma vez no Slack 11.0 e kernel 2.6.17.13, porem agora nao quer funcionar, retornando erro. antes de mais nada o basico da configuracao:

Dist: Slackware 12.2
Kernel: 2.6.30.5 (tambem deu mesmo erro na 2.6.27.7)
DRBD: 0.7.25

Minha intenção é colocar o DRBD dentro do Kernel == Patching DRBD into the kernel ==

Bom vai o que eu fiz até agora:

Meu kernel já possui o .config atual, pois fui eu quem compilei ele.

drbd-0.7.25# make clean

resultado ok, depois:

make KDIR=/usr/src/linux-2.6.30.5 kernel-patch

resultado ok também, ele gera o arquivo:

patch-linux-2.6.30.5-drbd-0.7.25

depois vem os comandos:

cd /usr/src/linux-2.6.30.5
patch -p1 < /root/install/drbd-0.7.25/patch-linux-2.6.30.5-drbd-0.7.25

Resultado é também ok, diz que fez o patch nos arquivos corretos.
Certo, depois eu dou um makemenuconfig e habilito o DRBD dentro do Device Drivers/Block Devices
E quando eu executo o make ele me retorna este erro:
