Hello Joe,

In next-20241213 I find 5143 occurrences with

git grep -ni 'gpl-2\.0+' | wc -l

e.g.

Documentation/bpf/prog_lsm.rst:1:.. SPDX-License-Identifier: GPL-2.0+
drivers/ata/sata_rcar.c:1:// SPDX-License-Identifier: GPL-2.0+

Some additions are quite recent:

$ git diff HEAD~100 | grep -i 'gpl-2\.0+' | wc -l
63

Best regards

Heinrich
