Well, it boots, and the dentry cache shrinks under memory pressure. So
it's not _totally_ untested now.

But I don't really see why it would fix Miklos' case. I think
select_parent() may still end up touching the d_lru list of something
that is on the 'dispose' list. So the patch looks like a nice cleanup,
but it seems to be independent of the issue Miklos found.

What am I missing now?
