Omit an extra message for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

Marcus,

If making changes like this I would suggest only sending one until
you have have a response from the relevant maintainer.

It would save you time as often these sorts of changes are
a matter of personal taste and weighing up of costs vs gains
- hence it is not obvious that they will be accepted.

The corresponding feedback can become more positive for such
a transformation pattern after a while, can't it?

Can the wording “WARNING: Possible unnecessary 'out of memory' message”
(from the script “checkpatch.pl”) be another incentive?

No. The key word is possible. Check patch is dumb and often gives false positives.

While it would be great to improve checkpatches false
positive rate, it's very nature as a string matcher makes
this hard.

This particular case is only 'sort of' a false positive
in the warning that a message printed on a memory allocation
failure 'may' not add any information over the generic case.

Very hard to judge on whether it is useful to know more than
an allocation failed somewhere or not.

Message makes this clear:
>“WARNING: Possible unnecessary 'out of memory' message”
>(from the script “checkpatch.pl”)  

We also have the balance between any changes to existing code
adding 'some' maintenance overhead vs changing this stuff
in a new driver - which is what checkpatch is really intended
for.

So I think checkpatch is striking the right balance here in
how it warns.  Obviously if it could assess the text
and come to an informed decision that would be great but
we are some way from that ;)

Right.  So it's not a 'false positive' at all.
Are there any actual 'false positives' you know of?

There's almost zero maintenance overhead here.
The time it takes for the back and forth
replies is likely larger.

The 'informed' bit is difficult as it is mostly
a political problem.

This particular message really is unnecessary as
the generic dump_stack on any normal allocation
(ie: without __GFP_WARN) already emits location
specific information.

Removing these messages can help make the kernel
image smaller and thereby help make these OOM
messages a tiny bit less likely.

I just wish Markus would improve his consistently
terrible commit messages that just restate the
action being done and detail _why_ a particular
thing _should_ be done.

His acceptance rate would improve as many of these
back and forth replies for what trivialities he
posts as patches would be minimized.
