I have no problem with adding a SPDX line to the top of this file, but
use "SPDX-License-Identifier: GPL-2.0-only" as I was very intentional
with the selection of GPL version 2 only when I published this code.

Furthermore, please do not remove the existing copyright text; although
it's just boilerplate for some, I was careful with the selection of
these words, and I worry the SPDX line only -- despite its useful
conciseness -- may lead to misunderstandings about my intentioned
license for this code.

For the time being, I can't Ack this patch with the changes it makes
currently:
