[PATCH] MAINTAINERS: adjust to clang-version.sh removal

[PATCH] MAINTAINERS: adjust to clang-version.sh removal

[Lukas Bulwahn]

Commit 6c8ad4427f6e ("kbuild: check the minimum compiler version in
Kconfig") removed ./scripts/clang-version.sh and moved its content to
./scripts/cc-version.sh.

Since then, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches    F:    scripts/clang-version.sh

The CLANG/LLVM BUILD SUPPORT section in MAINTAINERS intends to track
changes in ./scripts/clang-version.sh; as the file is removed, track
changes in ./scripts/cc-version.sh instead now.

applies cleanly on next-20210121

Masahiro-san, please pick this quick fix-up patch.

Good catch, Lukas.

As a tipp:
Next time you can pass '--subject-prefix="PATCH next-YYYYMMDD"' when
doing 'git format-patch ...' (or whatever you use to generate the
patch).

Cannot say if we can add a "Fixes:" tag with commit hash-id of
"kbuild: check the minimum compiler version in Kconfig" - this missed
that move.
Maybe Masahiro does a respin and can fold this into above commit?
That's not my decision.

I've never seen anyone use this prefix before.

What does the date really help?  In staging, we apply everything on top
of staging-next and if it doesn't apply then we don't investigate, we
just say "doesn't apply.  resend if needed".

We may as well just say [PATCH linux-next].  No one is ever going to
look up the date if it doesn't apply to the latest linux-next.

Is there an official rule to label patches for Linux-next?

Usually - when I was more active on Linux-next development - folks add
a "PATCH -next" to the subject.
Of course, this needs additionally a hint in the patch/commit message
against which Linux-next release it is applicable.
Linux-next releases are highly dynamic - a patch might be applicable
to one single "-next" release.
Git trees come and go - are resetted to an older version of a Git tree.

As LKML is CCed - think of the hundreds and thousands of patches
coming in daily.
So a more meaningful subject can give a first orientation.
That was my point.

Re: [PATCH] MAINTAINERS: adjust to clang-version.sh removal

[Dan Carpenter]

In networking then they want you to say which tree it applies to, but
it's not as simple as saying "net" vs "net-next".  If it's a bugfix then
you should write that against "net" but if it's a clean up or a fix to a
recent change then it should be written against "net-next".

Also linux-next is not necessarily the same thing as net-next.
Networking patches should be written against either net or net-next, not
linux-next.

BPF tried to implement similar rules to they're not big enough to impose
their own rules.  It's quite a big headache to try to figure out which
tree to use if you're like me and have no clue about bpf.

Anyway, the point of the net vs net-next is that devs are supposed to
figure out the exact tree and they're supposed to only write net-next if
it doesn't apply to net.

It's not clear to me the value of putting linux-next in the subject.
Doesn't everyone develop against the latest devel tree?  Certainly I
can't imagine any maintainers doing extra work to try figure out the
date of the linux-next release.  Surely, they just say "Doesn't apply to
foo-tree.  Resend if necessary."  That's the fastest and easiest
response when patches don't apply.

Masahiro cannot pick this up because the patch to add clang-version.sh
to MAINTAINERS is in mmotm.

I think the better solution is for Andrew to drop the current version of

maintainers-add-a-couple-more-files-to-the-clang-llvm-section.patch

and pick up the second one I sent, which allows us to deal with this:

https://lore.kernel.org/lkml/20210114171629.592007-1-natechancellor@gmail.com/

I am not sure it is right for us to maintain cc-version.sh but I am open
to it if Masahiro agrees.

Sounds like a good idea to integrate both patches from Lukas and
Nathan into a new version of "kbuild: check the minimum compiler
version in Kconfig".
...up to the maintainers.

Okay, I did not see in linux-next that both changes are coming into
linux-next through to different trees.

Nathan, I guess if you send a follow-up patch to Andrew that is the
best way to handle it, or we wait until both trees land in mainline,
and then just provide a quick fix like this afterwards.

So, Masahiro-san, no need to pick this patch here.

I agree.

I am not sure either.


The part in cc-version.sh maintained by Clang folks
will be this single line:

clang_min_version=10.0.1


You can add cc-version.sh to the coverage if you want.

Or, the following line in MAINTAINERS might be
enough to catch the clang version change.


K:      \b(?i:clang|llvm)\b



I will leave up to you guys.
