Hi Christoph!

Um, me too. I should have reposted my previous explanation, sorry!

Unfortunately, removal needs to be done in two stages, to sanely make
things like IPv6 modular (a deactivate, and a kill stage). It turns
out that this applies to loading as well, in case the loading fails
part way through (there's also a number of modules at the moment which
initialize in the wrong order, which can lead to an oops).

Firstly, Keith and I agree on KBUILD_OBJECT[/.]paramname, BTW. I'm
not sure it was his proposal originally, though: it's a pretty simple
and old idea.

The previous module param stuff was prone to user bugs (no type
checking), was not extensible, and required duplicated code for boot
time. It also did not have the option of appearing in /proc.

It is possible to write macros mapping the NEW macros to the OLD, but
not vice versa, otherwise I wouldn't change at all.

Hope that clarifies,
Rusty.
