Well, the patches look superficially cleaner to me, at least. That
"doesn't seem to be necessary" makes me a bit worried, and I'd have
liked to see a more clear-cut "clearing it isn't necessary because X",
but I _assume_ it's not necessary simply because the 'struct
address_space" is released and never re-used.

But making the lifetime of that bit explicit might just be a good idea.
