Subject: Re: [PATCH v3] powerpc/powernv: add NULL check after kzalloc in
 opal_add_one_export

>>>> Here needs a NULL check.
>> quite obvious?

I suggest to consider another fine-tuning for the wording also around
such “obvious” programming items.


>>> I find this change description questionable
>>> (despite of a reasonable patch subject).

I got further development concerns.

* Were changes mixed for different issues according to the diff code?

* I find it safer here to split specific changes into separate update steps
  for a small patch series.

* Will the addition of the desired null pointer check qualify for
  the specification of the tag “Fixes”?


>>> Will a patch change log be helpful here?
>> I realized I should write some change log, and the change log was meaningless.

Will any more adjustments happen for the discussed update suggestion
after the third patch version?

We might stumble on a different understanding for the affected “change logs”.

Would you like to follow the patch evolution a bit easier?
