FYI, the SPDX identifier GPL-2.0+ is deprecated as of 2.0rc2 [1]. I think you'd
need to use GPL-2.0-or-later [2] instead. And when using the SPDX identifier,
you don't need to include the full text boilerplate in the source of every file
as long as you include a LICENSE file or COPYRIGHT file with a copy of the
license. One example upstream here [3] commit 1a59d1b8e05ea ("treewide: Replace
GPLv2 boilerplate/reference with SPDX - rule 156").

[1] https://spdx.org/licenses/GPL-2.0+.html
[2] https://spdx.org/licenses/GPL-2.0-or-later.html
