I cannot parse what "documentation blocks" means in this context.  I
would maybe write this as:

"Previously this said it would only happen on barrier writes.  However
Linux blkback and possibly other backends already return it when the
type of the requests is unknown.

Fix the comment to clarify the return code can be used as a reply to
any request types not understood by the backend, not just barrier
writes."

Possibly with the commit message adjusted:

Thanks, Roger.
