Hi Harry,

these all look pretty good to me, have you tested them with lockdep enabled?

I had started to fix the CSN/GUID one here a little while back but it's sitting
on a laptop I can't access at the moment.

But if you can test with lockdep, and it doesn't deadlock, then I'm happy
to accept these..
