Thomas has sent a first doc patch [1] set and is working on an updated
version. Jonathan also wrote a nice background article on the topic
at LWN [2].
Linus explained why he wants the // comment style and a first line

Sorry for wrecking your workflow with a smallish comment related
comment and I am grateful that you consider this.
Thomas (tglx) is working on updated doc patches as soon as his real
time clock yields a few ticks for doc work...
The point is that Greg pushed already 10K+ file updates with proper
SPDX ids.... I chipped in a bit there and there are still eventually
60k+ files to go to have a uniform and simplified licensing
kernel-wide.
So, every little bit to help avoiding drift and regress is helpful.
Linus request for using // is to make this unambiguously greppable.
The selfish benefit to me is that eventually I will be able to send
to the trash my license scanner in the future [1] (we use it to help
cleanup the kernel FWIW) and replace this with a good' ole grep once
everyone on earth use clean and greppable licensing... The kernel is
setting the pace there for the whole FLOSS world and I hope this will
snow ball, but hope is not a strategy! Once the kernel is done, I will
have only more or less 100 billion+ file left to clean after that ;)

No problem, I understand your PoV even if the // comment is still dumb
to use in /* */ only commented files.

No problem, but maybe it would be time to actually tell all the maintainers
about this new policy, so we can start applying it.

Well the "SPDX-Licence-Identifier: (.*)$" seems pretty greppable for
me... anyway we will comply.
