I suggest to avoid a few typos in this wording.

I would appreciate answers to my remaining open questions.
https://lore.kernel.org/cocci/fb101290-3ec7-9170-9fec-43e1b5f54c52@web.de/
https://sympa.inria.fr/sympa/arc/cocci/2022-09/msg00022.html

Would anybody get into the development mood to generalise and extend the source code
search pattern besides proposed adjustments for the handling of two APIs?

How many data structures would need further initialisations after memory areas
were allocated?

Regards,
Markus
