Ok, so you are talking about using magic arch knowledge to know what
virtual address range might include the kernel mapping and finding a memory
region there. That is worse than the kallsyms heuristic I'm doing, for
purposes of making things reasonable in userland.



I understand that using /proc/kallsyms is much easier but it does not work
if somebody built a custom kernel without kallsyms support.


How often customers build their own custom kernels? If they do build, doesn't distro support contract gets void?
I personally think usefulness of kallsyms outweigh the risk of not supporting custom kernels.


Thanks
