Can you resend this series and just use the correct SPDX identifiers for
all of the new files, instead of all of this horrid boiler-plate code?

That will save me time when I have to go delete all of this in the near
future :)

Also, why dual license it?  Are you _SURE_ you want to do that, and are
totally aware of all of the crazy issues surrounding it?  Hint, it
almost never means what you might think it does, and I have yet to know
of anyone doing anything "real" with any dual-licensed Linux kernel
code.

Remember, BSD is not the license you want/need for GPL header files that
are exposed to userspace...


thanks,
