The shown source code transformation approach can be repeated on demand
for selected areas.

Another test result (according to the software combination =E2=80=9CCoccin=
elle 1.3.1=E2=80=9D):
Markus_Elfring@Sonne:=E2=80=A6/Projekte/Linux/next-analyses> time /usr/bin=
/spatch --timeout 23 -j4 --chunksize 1 --no-loops --include-headers -dir t=
ools/bpf/bpftool /home/altes_Heim2/elfring/Projekte/Coccinelle/janitor/use=
_fputc-20260723.cocci > /home/altes_Heim2/elfring/Projekte/Bau/Linux/scrip=
ts/Coccinelle/tuning1/next/20260721/use_fputc-bpftool-2.diff
=E2=80=A6
17 files match
=E2=80=A6
real    0m1,998s
user    0m4,143s
sys     0m0,372s



Now I wonder about the following information.

Markus_Elfring@Sonne:/home/altes_Heim2/elfring/Projekte/Linux/next-analyse=
s> grep 'diff -u -p a/netlink_dumper.h b/netlink_dumper.h' /home/altes_Hei=
m2/elfring/Projekte/Bau/Linux/scripts/Coccinelle/tuning1/next/20260721/use=
_fputc-bpftool-2.diff | wc -l
2


Should it be sufficient to adjust an affected header file only once
(according to the means of the mentioned development tool)?
