> Changes since v1:
>
>   - Rebased on 4.1-rc3
>   - Transport fault injector controlled from debugfs rather than /proc
>   - Transport fault injector works for all transport types
>   - bc_send() clean up suggested by Christoph Hellwig
>   - Added Reviewed-by: tags. Many thanks to reviewers!
>   - Addressed all review comments but one: Sagi's comment about
>      ri_device remains unresolved.
