I read the patch. It was quite monotonous (I guess that's a good thing)
But it wasn't clear to me why you added the INIT_LIST_HEAD()s
everywhere. Is this for stopping parallel walkers?

Ok there's a comment in the doc: "VFS expects it to be initialized"
Is that really true today? I don't think the old code does that.

Other than that it seems straight forward.
