I couldn't care less about bpf, this is about the kernel API.
What I mean is that your new probe_kernel_read_strict and strncpy_from_unsafe_strict helpers are good and useful. But for this to actually make sense we need to get rid of the non-strict versions, and we also need to get rid of some of the weak alias magic.
