Add buffer IO isolation based on v2 infrastructure to v1, so we
can unify the interface for dio and bufio.

Christoph Hellwig 6dfbba543a bdi: move bdi_dev_name out of line 
[ Upstream commit eb7ae5e06bb6e6ac6bb86872d27c43ebab92f6b2 ]

bdi_dev_name is not a fast path function, move it out of line.  This
prepares for using it from modular callers without having to export
an implementation detail like bdi_unknown_name.
