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.
