deal with rbtree.

Christoph Hellwig 4e4cbee93d block: switch bios to blk_status_t 
Replace bi_error with a new bi_status to allow for a clear conversion.
Note that device mapper overloaded bi_error with a private value, which
we'll have to keep arround at least for now and thus propagate to a
proper blk_status_t value.

Joe Thornber 742c8fdc31 dm bio prison v2: new interface for the bio prison 
The deferred set is gone and all methods have _v2 appended to the end of
their names to allow for continued use of the original bio prison in DM
thin-provisioning.
