You are hitting problem with backporting some of the kernel patches and each
distro handles it differently. Linux kernel changed the layout of 'struct
module' via dollowing patch:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/diff/include/linux/module.h?id=7523e4dc5057
(among other for better caching) but many distros may or may not backport this
patch to own kernel tree for other kernels as well. LKRG takes this into
account and this patch is handled by comparing which version of the kernel tree
supports it via:
file "lkrg-main/src/modules/kmod/p_kmod_wrapper.c"
#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 4, 6)
...
#else
...
#endif
It look like your kernel tree doesn't have that patch yet, so the easiest
option is to change this line:
#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 4, 6)
to be e.g.:
#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 5, 0)
and it should compile correctly. We can't do it for the official LKRG
repository because other kernel will have opposite problem.
Thanks,
Adam
