It's not a valid reason to export them as GPL. Entire Linux source code
is licensed as GPL-2.0, so are you going to change all EXPORT_SYMBOL to
GPL?

Please describe it better. Usually the symbols are exported as GPL if
they are considered tightly coupled with the kernel code. So tightly
that basically it is not a interface anymore but part of kernel
internals and therefore any usage of it is a derivative work of Linux
kernel. If this is the case here, please describe in commit msg why
these match this criteria.

Best regards,
Krzysztof
