So strictly speaking the existing annotation is also ok, because we have a chain of obj->mm.lock#I915_MM_GET_PAGES -> fs_reclaim -> obj->mm.lock (the shrinker cannot get at an object while we're in get_pages, hence this is safe). But it's confusing, so try to take the right subclass of the lock. This does a bit reduce our lockdep based checking, but then it's also less fragile, in case we ever change the nesting around.
