> Yes, for the discussion when to use I'd propose to *not* use kconfig if:

> * boot parameter to enable/disable exist
> * check for tristate (functionality which can be compiled as module)
> * kernel new functionality which is unlikely to be backported (use .min_kver instead)

That sounds great to me.

And, plus one more:
   * kconfig file may be unavailable for some reasons
