I see a need to improve not only correctness there but also a bit of
software efficiency.

If you can measure any performance difference and present some results
(esp. considering that this is something that just happens when the
driver is loaded), then we'll talk.

Are you really interested to increase your software development attention
for a quicker exception handling implementation in this function?

Until then, please don't send this sort of patch.  Thank you.

Will benchmark statistics change such a change rejection ever?
