MIT-licensed code should be just fine with GPL symbols, just use the
correct MODULE_LICENSE() setting and all is good.

As all of the previous kref functions were in a GPL-only header file,
and included directly that way, they were already GPL-only symbols, so
there really was no change here except now the linker checks them. If
you have questions about using inline GPL-only functions from a .h file,
in a non-GPL codebase, please consult your corporate lawyer to get
clarification.

thanks,
