Absolutely. That's one of the issues with these patches. They don't even
try where it's absolutely possible.
Are you referring to blocking the maps of the msix BAR areas?
I think there is value in that. The value is small, because a
corruption is more likely in the dynamic memory responsible for tens of
millions of DMA operations per second, rather than a static 4K area, but
it exists.
