Ahh. Those I can believe in. Although I think they'd almost
incidentally be fixed by making inode freeing (which is where the
'struct address_space' is embedded) RCU-safe, which we're going to do
anyway in 38. Then we could make the vmscan code just be a rcu-read
section.

Of course, I do think the race is basically impossible to hit in
practice regardless.
