Sorry, but I have to register extreme distress at the name of this.
The term "bio" is well-established in the kernel and here we have a new
definition for the same term: "block I/O".
"bio" was a fine term for you to have chosen from the user's
perspective, but from the kernel developer perspective it is quite
horrid. The patch adds a vast number of new symbols all into the
existing "bio_" namespace, many of which aren't related to `struct bio'
at all.
At least, I think that's what's happening. Perhaps the controller
really _is_ designed to track `struct bio'? If so, that's an odd thing
to tell userspace about.
Presumably it tracks all forms of block-based I/O and not just delayed
writeback.
