Subject[PATCH] Revert "regulator: core: Add support for active-discharge configuration"
Message-ID<rgjAf-7ve-45@gated-at.bofh.it>
This reverts commit 909f7ee0b5f30f735e16864a7ed18d2e6123e6d9.

Apparently due to a wrongly resolved merge conflict between two
branches, which contained the same commit, the commit contents
partially was added two times in a row.

This change reverts the latter wrong inclusion of commit 909f7ee0b5f3
("regulator: core: Add support for active-discharge configuration").

The first applied commit 670666b9e0af ("regulator: core: Add support
for active-discharge configuration") is not touched.

Please submit patches using subject lines reflecting the style for the
subsystem.  This makes it easier for people to identify relevant
patches.

I agree, but the subsystem name is found in the name of the reverted commit.

% git log --oneline | grep ' Revert "' | head -n 100

shows that only 1 of 6 revert patches has subsystem name in subject two times.

Do you ask me to resumbit the change changing the subject to
'regulator: core: Revert "regulator: core: Add support for active-discharg
 configuration"'?

That doesn't help if it's not at the start of the subject line of the
e-mail.

Well, I applied it already so no but in future yes, reverts are patches
like any other and should follow exactly the same process.

Okay, submitting of reverted patches is different I believe:

http://www.spinics.net/lists/arm-kernel/msg75667.html

RMK:

    I think it's sensible to keep at least the summary line of
    a 'git revert' intact rather than inventing our own.

That discussion was about a8cf81ffe028 '(Revert "[ARM] unconditionally
define __virt_to_phys and __phys_to_virt")'

Nope, they're patches like other patches.  A big part of what the
subject line does is help people work out what they need to look at,
something that doesn't pattern match doesn't fulfil that need.

regarding pattern matching just remove ^ from the regexp and people
be aware of this "regulator: core" change.

I understand that the reverted commit is a maintainer's fault and by
renaming the subject you may hide it, so talking about people needs
please let them know that the change _reverts_ another commit.

I can not add Fixes: tag, because the change does not fix a commit, and
there is no Reverts: tag due to its obvious redundancy.

Please look at 1 hour old 1701f680407c ("Revert "ppdev: use new parport
device model" ") --- that's IMHO the proper way to create and apply
reverts.

And I disagree with the modified subject and commit message done by you
and without a notice mentioning this your change in the commit message.

The pattern matching in this case is typically being done by human
beings.

The fact that a change happens to have been generated with a revert has
no technical impact, you're not communicating with machines here but
rather with people.  Yes, some people don't mind especially if they're
just directly publishing the commit (where it matters much less) but
that doesn't override all other considerations.

I already published it so it's a bit late now.

#1364772 — Applied "regulator: core: Remove duplicate copy of active-discharge parsing" to the regulator tree

FromMark Brown <broonie@kernel.org>
Date2016-03-25 17:50 +0100
SubjectApplied "regulator: core: Remove duplicate copy of active-discharge parsing" to the regulator tree
Message-ID<rgD5U-4yf-13@gated-at.bofh.it>
In reply to#1364419
The patch

   regulator: core: Remove duplicate copy of active-discharge parsing

has been applied to the regulator tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
