I understand your need here, however we do not export things for modules, when there are no in-kernel module users, sorry.
I have your last thread somewhere in my todo pile, to try to respond as to how to make this not be an issue for you, sorry I haven't gotten to it.
Why can't you just add a tracepoint instead of having to dig through this mess? Wouldn't that solve a lot of these issues for block devices?
thanks,
