Re: lua(4), non-invasive and invasive parts

this is going to upset dyoung i'm sure :) but it seems to me that
if these invasive changes to individual subsystems are needed like
this, and we want them to be optional, then imo they should be on
a per-subsystem basis, not global.  eg something like:

        options LINEDISC_LUA
        options GPIOSIM_LUA

etc.  the ugliness could/should be largely hidden in header files.

The problem remains that modules no nothing about kernel options. Maybe - in an ideal world - there should be no kernel options at all, but only modules... ;)

Perhaps I'm missing something obvious, but why can you not have your line-discipline module simply depend on a lua module? Then you no longer need to know if the kernel "has lua" because it can always "get lua when it needs it".
