Please can you repost with your Signed-off-by line added to the patch? I
can't merge anything from you without that.

I think it would also be a good thing to have a little more information
about how this is being used in driver modules.

If it's for ad-hoc debugging, then I see no reason for it to be merged
into mainline kernels just for the utility of people adding code to
drivers to perform that debug - they might as well temporarily add the
export at the same time IMHO.
