[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 22 Apr 2017 23:00:23 +0200

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "devm_kcalloc".

* Replace the specification of a data structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

I have trouble parsing that sentences. This looks like the typical
approach of native german speakers to directly transfer sentence
constructions from German to English. Which, in most cases, doesn't work
or is just plain confusing.

Do you find the following wording better to understand
if it would be presented by a script like “checkpatch.pl”?

WARNING: Prefer devm_kcalloc over devm_kzalloc with multiply

For example. Also I just noticed some previous comment by Krzysztof that
pointed that out already.

My suggestion: One sentence describing that the current situation is.
Another sentence explaining why this is bad/undesirable. Last sentence
saying what you're doing to fix this (can sometimes be omitted if it's
clear from the diffstat). In this case, the output of the checkpatch
script would come in handy.

With this, you avoid cramming every information into one long and
complicated sentence.

Tobias

Why do you find the sentence for the multiplication information inappropriate
(or incomplete) at the moment?


> Another sentence explaining why this is bad/undesirable.

Which details do you miss here?


> In this case, the output of the checkpatch script would come in handy.

Its implementation of the check “ALLOC_WITH_MULTIPLY” considers only an other
search pattern so far.

* Do you find it worthwhile to add a prefix like “devm_” to the used
  regular expression?

* Would like to improve any related scripts for the semantic patch language
  (Coccinelle software) a bit more?

s3c24xx: Use devm_kcalloc() in s3c24xx_dma_probe()

Why do you find the sentence for the multiplication information inappropriate
(or incomplete) at the moment?

Which details do you miss here?

Its implementation of the check ?ALLOC_WITH_MULTIPLY? considers only an other
search pattern so far.

* Do you find it worthwhile to add a prefix like ?devm_? to the used
  regular expression?

* Would like to improve any related scripts for the semantic patch language
  (Coccinelle software) a bit more?

I already explained that. It's a 1:1 translation of a german sentence
into English. A native speaker does not write or speak like that. If in
doubt, don't use long sentences (with nesting, etc.) at all, and break
things down into logical blocks.

Pretty much everything.

I don't understand why you're asking this. I'm talking about the
_output_ of checkpatch, not about the script itself.

But undoubtedly your patch is motivated by the output of said tool.
Hence you should mention that.

Software developers and code reviewers have got different opinions
about such checks and their relevance.


> I'm talking about the _output_ of checkpatch,

This information is clear at first glance.


> not about the script itself.

But it will not provide the warning you might be looking for
while you seem to find my source code analysis approach and
notifications improvable.
I assume that you might be interested in corresponding extensions
for the involved search patterns.

Additional tools take also care for similar software development concerns,
don't they?

Can it be appropriate to omit the reference to only one Perl script
for related use cases?

Markus
