Subject: Compiling issue on Debian 9 with vanilla kernel 4.18.9

Hi,

when I try to compile the latest lkrg version on my debian 9 systems i run into error. I am running the latest vanilla kernel 4.18.9 and I am using gcc 7.3.0.

root@...ian9:/usr/src/download/lkrg-main# make -j4

I already modified src/modules/integrity_timer/p_stext_diff.c to get rid of the "‘JUMP_LABEL_NOP_SIZE’ undeclared here…” error, which was already discussed on the mailing list.

Any idea of what might be the problem?

Many thanks & Regards,
