BTW, the declarations of those functions in the kernel are a bit
different from the rest. My grep_syscall function couldn't find them.
There's no sys_inb, nor does it use SYSCALL_DEFINE?().

There are a lot of different declarations like plain 'inb' (some static,
some extern). Where is the actual syscall defined?

Thanks,

Alex
