[etc...]

> Why, and why these in particular?

bool functions are probably better returning
bool values instead of 1 and 0.

Especially when the functions intermix returning
returning 1/0 and true/false.

(there are only a couple of those though)

These are all the remaining instances in the
kernel tree.

bool functions are probably better returning
bool values instead of 1 and 0.

Especially when the functions intermix returning
returning 1/0 and true/false.

(there are only a couple of those though)

These are all the remaining instances in the
kernel tree.

Hey Ben.

I don't merge stuff.  I just send patches.
So, it'll be better if you do it.

I'll resend whatever doesn't get picked up in
the next couple months on to Andrew Morton.

Joe, as has been *repeatedly* requested you should use subject lines

separate patches consider sending that way).

I'm missing a why; why are you doing this?

Let me guess: Joe Perches is suffering from 'trivialititis': a 
sickness that prevents a non-newbie kernel developer from raising 
beyond churning out a flood of trivial patches and creating 
unnecessary churn for other developers with these borderline useless 
patches?

Linux is a meritocracy, not a bureaucracy.

Thanks,

	Ingo

It's just a trivial little consistency patch to
make bool functions return bool values instead of
1 or 0 (even though of course 1 and 0 are the
values for true and false)

There's something like 13000 uses of return true
or return false in the tree vs these 180 or so
uses of 1 and 0.

Looks simple enough, I'll pick it up for 4.1.

Good morning Ingo.

As you are a signer of that "code of conflict" patch,
I'll be mildly amused, but not surprised, if you are
among the first participants.

Perhaps you can search for your own name here.

Hi Joe,

The boolean logic was reversed in this comment. The function should be
returning false if a decrement cannot be done without blocking, and
true if a decrement succeeded.

So as a reply to my joke directed against your (costly: see below) 
flood of trivial and somewhat bureaucratic patches that PeterZ 
complained about, which reply of mine aimed at getting you to change 
from your many years old pattern of producing trivial patches towards 
producing more substantial patches, causes you to issue a threat of 
bureaucratic action against me?

Wow.

I'd also like to stress that I don't think you have answered PeterZ's 
legitimate technical question adequately: what are the technological 
justifications for doing this 25 patches series - returning 0/1 or 
true/false is clearly a matter of taste unless mixed within the same 
function. In fact what are your technological justifications for doing 
so many trivial patches in general?

Please don't bother producing and sending me such trivial patches 
unless they:

  - fix a real bug (in which case they are not trivial patches anymore)

  - or are part of a larger (non-trivial!) series that does some real,
    substantial work on this code that tries to:

         - fix existing code

         - speed up existing code

         - or expand upon existing code with new code

         - turn totally unreadable code into something readable
           (for example in drivers/staging/)

The reason I'm not applying your patch is that trivial patches, even 
if they seem borderline useful, with no substance following them up, 
often have more costs than benefits:

 - they lead to pointless churn:

    - they take up Git space (and bandwidth) for no good reason

    - they slow down bisection of real changes

    - they take up (valuable!) reviewer bandwidth

    - they take up maintainer bandwidth

there's literally a million borderline pointless cleanup patches that 
could be done on the kernel, and we really don't want to add a million 
commits to the kernel tree...

I don't think your 25 patches long trivial series is defensible from a 
kernel contributor who has thousands of commits in the mainline kernel 
already: you are clearly not a kernel newbie anymore who needs to 
learn the ropes through simple patches and whose initially trivial 
patches maintainers will nurture in the hope of gaining a future 
contributor who will be a net benefit in the future...

I also think you are beginning to abuse the openness of kernel 
maintainers to apply trivial patches, and I don't think it's useful to 
point out such abuse before it gets worse.

My (repeated) advice to you is that you should try to raise beyond 
newbie patches and write something more substantial that helps Linux:

 - take a look at the many bugs on bugzilla.kernel.org and try to 
   analyze, reproduce or fix them

 - go read kernel code, understand it and try to find real bugs.

 - go test the latest kernels and find bugs in it. The fresher the 
   code, the more likely it is that it has bugs.

 - go read kernel code and try to expand upon it

Fortunately it's not hard to contribute to the kernel once you are 
beyond the 'newbie' status: there's literally an infinite amount of 
work to be done on the kernel, and I welcome productive contributions 
- but churning out trivial patches with no substantial patches 
following them up is not productive and in fact (as pointed out above) 
they are harmful once you are not a totally fresh newbie kernel 
developer anymore...

Pointing out this truth and protecting against such abusive flood of 
trivial patches is not against the code of conduct I signed.

Thanks,

	Ingo

Not to mention that one of your trivial patches in this series 
actually introduced a bug:

  lkml.kernel.org/r/1427867186.18175.60.camel@perches.com

Which additional risk adds to the cost side of the equation as well.

I totally agree, it's not "against" the code of conflict that I helped
write.

Joe, you know better than to send trivial stuff to maintainers who don't
want it.  Send it through the trivial maintainer for subsystems that
have expressed annoyance at this, it's not the first time this has
happened.

Some maintainers, like me, are fine with your types of patches, I'd
stick to those subsystems if you like doing this type of work.

Also, don't send stuff that is broken, that's not the sign of a trivial
patch :(

thanks,

I argue that they should not be sent _at all_ in such cases, not even 
via the trivial tree: firstly because typically I'll pick up the bits 
from the trivial tree as well, and secondly because most of the 
arguments I listed against bulk trivial commits (weaker bisectability, 
taking up reviewer bandwidth, taking up Git space, etc.) still stand.

Frankly IMHO such a */25 series could be a net negative contribution 
when coming from a kernel contributor who has written 2000+ trivial 
patches already...

So sending trivial patches for things like totally unreadable code in 
say drivers/staging/ is probably OK, as they materially transform the 
code and make it more maintainable.

For the rest it can be more harmful than beneficial, for the reasons I 
outlined.

Thanks,

	Ingo

I agree, I do not want actual code changes to by-pass me for the
subsystems I'm responsible for.

Typoes in comments I can live with, but I want to see each and every
patch that changes actual code.

Can't we send all these kind of patches through the trivial tree?
Don't get me wrong, if you are fine with these patches that's you decision.
But other maintainers might think they have to take these patches and
get overloaded. I'm thinking of drivers maintainers that can only work
one or two hours per week on Linux.
Not everyone works full time on it like you.

I propose to send all this stuff though the trivial tree such that maintainers
of other subsystems have less workload and newbies (which are supposed
to send such patches) know which tree they have to work against.
Let's have to well defined and ordered. :-)

As per the other branch of this tree; an emphatic NO to that. The
trivial tree is not a backdoor to bypass maintainers. Actual code
changes do not get to go through any tree but the maintainer tree unless
explicitly ACKed.

I agree that the series in question is useless.
But if a patch is trivial it can go through the trivial tree.
By trivial I really mean *trivial* in terms of typos
and 80 character limit crap.
It has to be something which does not hurt and the maintainer
can safely ignore.

Well, practically speaking, that would make changes like the recent
clockevents_notify() removal very difficult to carry out.  Also there is
some natural cross-talk between certain subsystems.

Different matter is the real value of tree-wide cleanup changes.  If code is
old enough it often is better to leave it alone, even though it may be doing
things that we don't usually do nowadays.

Or things that new patches are not supposed to do, for that matter, so
I generally don't like the "checkpatch.pl error fix" changes in the old code.

I presume you mean file rather than function.

21 of the 55 files modified already used "return true"
or "return false" for other bool function returns.

Many of the 1/0 uses were in functions where the
function return type was changed from int to bool but
the return statements were unchanged.

Expectation and consistency matter.
To what degree is, as always, debatable.

Code that causes a reader to "stall" when reading is
generally not good.  

Patches that span subsystems, given the distribution
of interest and responsibilities in the kernel,
generally aren't possible to apply by any single
maintainer.

It's generally necessary to split even these admittedly
trivial patches by area of maintainership.

Bypassing actual maintainers by sending only to the
nominal trivial maintainer isn't good.

Consistency improves reading speed and can help reduce
future defects.

> Please don't bother producing and sending me such trivial patches

My creation of these types of patches either singly
or in a series is fairly automated.

I will sed your name and email address out of the
scripts that generate the "To:" and "CC:" lists for
patches in the future.

If any other person with a MAINTAINERS entry wants not
to receive these types of patches from me, please let
me know privately.

Jokes are hard.
"Be excellent to each other" can be too, but shouldn't be.
Manners and civility are important.
Yours, like mine, can always be improved.
We all should strive for that improvement.

Only if they received an Acked-by from the maintainer of the code that 
it touches. That way, Peter does see the code that is changing. He doesn't
need to take it through his tree, but the trivial maintainer must get his
Acked-by, which shows that he did actually take a look at the patch and is
fine with it going through another route.

Egad no. The 80 character limit is a guideline not set in stone. There's so
many times I see people break up lines to avoid that limit and make the
code uglier and more difficult to read. Again, that's a trivial change that
would do more harm than good.

I think the only change that could probably go in without an ack from the
maintainer is a change that Peter already mentioned. Typos in comments that
do not touch the actual code.

I would not call the clockevents_notify() series "trivial". More advanced
clean ups that are system wide, would be different, because you are changing
the way the code works. The maintainers must be Cc'd, but sometimes I find
those changes are very hard to get acks from everyone. But again, the change
is a non trivial clean up and has other reasons for going in than just to
make the code look nice.

Or maybe it's a good time to rewrite that code such that everyone can understand
it today ;-)

I totally agree with that. But for non trivial clean ups, old code should be
updated too.

Agreed, I don't want trivial patches to ext4 either (a) polluting my

Well, there still is some risk of introducing real bugs this way (I *have* seen
"trivial cleanups" that broke things) and is it really worth it?

Besides, old code is somewhat like an ancient building.  Yes, it needs to be
kept in a good shape, but you won't replace bricks in it just because they are
old, will you?

No, but you do have to replace/repoint the mortar
as it ages.

Here in SoCal, we also have to do structural work
on UnReinforced Masonry (URM) buildings to avoid
loss of life when the ground moves underneath us.

A small story:

There's a guy a few blocks from me that wants to
open a restaurant in a ~70 year old building.  He's
been fighting the city permitting process for over
a year now because he rented a well built, but old,
URM building with double courses of brick walls
that had already had some structural improvements.

http://la.eater.com/2014/3/18/6260975/brixton-restaurant-going-into-the-joker-in-santa-monica

He added some windows where previously windows had
been located but also had been covered and filled-in
with over time.  The place had been a dark, smoky
dive bar.

City went into a mode where any change to the
building was unacceptable unless _every_ element
of the building was brought up to new construction
standards.

It's a silly and expensive process for him and an
overall loss for the city because of delays in
creation of a tax-paying business.

Santa Monica, my home town...

Anyway, code isn't a lot like a building.

It's easy to prove that some source code change
doesn't cause a change in object output.

It's not so easy in a physical structure.

When they matter to the integrity and they are likely to be full of
internal cracks and holes you do.

What concerns me more is that we now have lots of old driver code in the
kernel that nobody uses, that nobody cares about in reality but which has
been turd polished to the point that at casual glance it looks maintained
and useful but probably hasn't been tested in years.
