It looks like this way we mangle the anon_vma chains somehow. From what I can see and if I'm not mistaken, we save the anon_vmas alright but end up in what seems like an endless list_for_each_entry() loop having grabbed anon_vma->lock in page_lock_anon_vma() and we can't seem to yield it through page_unlock_anon_vma() at the end of page_referenced_anon() so it has to be that code in between iterating over each list entry...
