If you're ok with my patch (it's now also tested, I'm running with it
and it looks fine), I'll commit that one as-is.

When you say "those two diffs of yours", which two are you talking
about? I already committed the "dead lockref" part separately - it may
be "preparatory", but it was preparatory cleanup that didn't change
semantics, so it's better to be separate anyway. The last patch I sent
out a few moments ago is the one that actually fixes things so that
"dput()" isn't done under the RCU lock etc.
