I'll have to see where I left off. I'm a bit ADHD when it comes to some
of my projects. I work on them for a bit, then the next day I'll go work
on something else. Eventually all my projects get done (well, I like to
think they do ;-)

I'm currently working on a nasty bug that's in mainline when you enable
both LOCKDEP and FUNCTION_TRACING. I've been at it since Thursday (even
worked a bit over the US holiday here). I'm hoping I have a working
solution for it today. But I can't work on anything else till this is
complete.

After I get this bug fixed, I can take a look at the multi select code I
have.

Thanks,

-- Steve
