This is based on commit "LSM: Identify modules by more than name" https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v6.8&id=f3b8788cde61b02f1e6c202f8fac4360e6adbafc

Which is a requirement to build on kernel 6.8+. I use 912 as the ID for KernelSU as that's the date the Github repo was created.

Extra patches might be needed, but this is directly into the kernel
https://elixir.bootlin.com/linux/v6.8/source/security/security.c#L55
Basically add CONFIG_KSU into LSM_CONFIG_COUNT define. I think we might have to update the wiki for this @tiann

This won't work for LKM mode, we need another solution.

Find a way to reduce lsm active count to make it lower than LSM_CONFIG_COUNT and then load the LKM ?
