Several software development discussions might be interesting
also before the change “dma-mapping: remove dma_zalloc_coherent()”.

How do you think about the extend the software development background
another bit?

Do you refer to your response from 2020-04-07?
https://systeme.lip6.fr/pipermail/cocci/2020-April/007102.html

* You proposed a change for this SmPL script which contains programming mistakes.

* Would you like to achieve the restore of a SmPL code variant
  from a published patch hunk instead?

* Will the software development attention grow also around the recurring topic
  “Code duplications in SmPL disjunctions”?
