Subject: mm: export bdi_unregister

Patch series "simplify bdi unregistation".

This series simplifies the BDI code to get rid of the magic
auto-unregister feature that hid a recent block layer refcounting bug.


This patch (of 5):

To wind down the magic auto-unregister semantics we'll need to push this
into modular code.
