Re: [PATCH RFC] Restrictions on module loading

> NAK - Its a long standing ABI.

As far as I can tell, modules_disabled was first included in 2.6.31, so
it's hardly what I'd call "long standing".  However, I see your point -
it's definitely not my intention to surprise anyone by changing security
features out from under them.

I do think merging the features makes sense in this case.  I'll rework
this to keep the "modules_disabled" name, where a value of "0" means
default behavior, a value of "1" means no loading or unloading (and no
changing it back), and the new value of "2" incorporates the
restrictions I'm intending to enforce.

There has been interest in improving the ease with which users can
enforce restrictions on automatic module loading.  No one is being
forced to use it.
