Hmm?   Isn't there an API in the kernel being used to install a new syscall?

While I don't much believe in LKMs for available source systems, I do
however understand what you're requesting I think - that is, a more finely
grained way to tell just what API may have altered, so LKMs could
determine whether they will still work, or need to be recompiled.  The
current "nothing has changed" (which is often a lie anyway), or "anything
might have changed" is a little crude.
