These comments are bogus.
I guess this comment header was copied from QEMU,
but you changed the file path
from scripts/git.orderfile to scripts/git.orderFile.
You need to adjust the comment lines to
git diff -O scripts/git.orderFile ...
git config diff.orderFile scripts/git.orderFile
Or, you need to get the file path back to scripts/git.orderfile

Kbuild* and Makefile* are interchangeable.
(both are for GNU Make)
Kconfig* are different types.
Better to arrange the order to
Kconfig*
Kbuild*
Makefile*
> +*.mak
QEMU consistently uses only *.mak.
I just realized the kernel tree uses both *.mak and *.mk
masahiro@zoe:~/ref/linux(master)$ find . -name '*.mak'
./tools/scripts/utilities.mak
masahiro@zoe:~/ref/linux(master)$ find . -name '*.mk'
./tools/testing/selftests/lib.mk
./tools/testing/selftests/ptp/testptp.mk
BTW, I quickly tested this, but
it did not work as I expected.

My expectation was the following:

drivers/Makefile
drivers/cache/Makefile
drivers/cache/ax45mp_cache.c
It did not work like that.
Am I missing something?

Oh, you are right.

Yes, I tried to adapt it from QEMU to kernel needs.

Sure, I will add '*.mk' after '*.mak', getting:
# build system
Kconfig*
Kbuild*
Makefile*
*.mak
*.mk

I can reproduce this same behavior for this commit list, and this is odd.
When I added a line-end at the .c extension, it works as expected:
*.c$
I think this makes sense.
Just to make sure, I will add an line-end at every pattern with extension:
*.h$
*.c$
*.mk$
and so on.
Does that work for you?
I will send a v3 soon.
Thanks!

Oh, nevermind. This breaks the matching, and results are crazy.
I will revert it on a v4.
The real solver is:
*/Kconfig*
*/Kbuild*
*/Makefile*
The thing is that if I add just "Kconfig*" it only matches a Kconfig* in
the root dir.

I was talking on a previous thread, and it would probably be interesting
to add "*types.h" before *.h.
I need to think about a way to filter them out when matching "*.h", or it
won't work because of:
Git doc:
"The output order is determined by the order of glob patterns in <orderfile>.
All files with pathnames that match the first pattern are output first, all
files with pathnames that match the second pattern (but not the first) are
output next, and so on."
i.e. the file will be put in the category of the last pattern it matches,
and it makes harder to get "*types.h" before "*.h".
Trying to think on some solution.
