Subject: [PATCH v1 0/4] docs: stable-kernel-rules: fine-tuning and 'no semi-automatic backport'

After a recent discussion regarding "do we need a 'nobackport' tag" I
set out to create one change for stable-kernel-rules.rst. This is now
the second patch in the series, which links to that discussion; the
other stuff is fine-tuning that happened along the way.

Ciao, Thorsten

Fine-tuning:

* s/Linus' tree/Linux mainline/, as mainline is the term used elsewhere
in the document.

* Provide a better example for the 'delayed backporting' case.

I do not know what "stable mainline release" means here, sorry. "after
4 weeks in mainline" means "after in Linus's tree for 4 weeks, but
Linus's tree is not "stable mainline".

I meant a proper mainline release like 6.7 or 6.8 to make it obvious
that this does not mean a "pre-release".

I actually had used the term "proper mainline release" earlier in a
draft, but a quick search on the net showed that this is not really used
out there. "stable mainline release" is not popular either, but seemed
to be a better match; I also considered "final mainline release", but
that felt odd.

It feels like there must be some better term my mind just stumbles to
come up with. Please help. :-D

Well, what is the goal here? Just put it in words, I have seen stuff
like:
Cc: <[email protected]> # wait until -rc3
Cc: <[email protected]> # wait until 6.1 is released
Cc: <[email protected]> # after -rc2

and so on.

Just pick a specific time/release might be better? "after X weeks" is
assuming that we all know and remember how many weeks something
happened...

I've normally seen patches end up in Linus's tree "too early" more often
(i.e. cc: stable for stuff that has never been in a stable tree yet),
but sure, I can see how changes can also take too long.

Yes, referencing off of a fixed point like a release is best as that's
much easier for humans to calculate.

Also because, the original "after 4 weeks", doesn't give me a reference
point to judge what the starting time is easily. Yes, I have tools for
that, but most people don't.

So how about changing it to use the "fixed point" reference please? The
phrasing "after -rc3" is probably what most people almost always want
anyway, given the huge churn that -rc1 is.

thanks,

My reasoning was: a developer that submits a patch has no full control
over when the patch mainlined -- and plans sometimes change, too.

So a patch that was meant to go into 6.1-rc with a tag like "# wait
until 4 weeks after 6.1 is released" might only be mainlined for 6.2-rc1
-- and then the tag does not express the developers intention.

But that might be a corner case that we could ignore. So maybe "# wait
until 4 weeks after 6.1 is released" is the better example (from what
I've heard something like that is what developer would like to have
sometimes).

Ciao, Thorsten

Okay, will go with that phrase in v2; people that want to express "four
weeks after the change hit a proper mainline release" (I've seen a few
people want something like that to ensure it gets field testing in a
real release) can then add a version number to it.

Thx! Ciao, Thorsten
