NACK.


This is because you are doing *WRONG* in 3/3.

Look at your code closely.

https://lore.kernel.org/linux-kbuild/20231104194207.3370542-4-sjg@chromium.org/T/#me2fb68151d6f4f330808406f9a711fffee149529



In the mainline kernel, the quotation appears
only in the definition of UIMAGE_NAME.


masahiro at zoe:~/ref/linux(master)$ git grep UIMAGE_NAME
scripts/Makefile.lib:UIMAGE_NAME ?= 'Linux-$(KERNELRELEASE)'
scripts/Makefile.lib:                   -n $(UIMAGE_NAME) -d $< $@


The single quotes are consumed by shell.






This is mainline + your patch set.

masahiro at zoe:~/ref/linux(simon-v2)$ git grep UIMAGE_NAME
scripts/Makefile.lib:UIMAGE_NAME ?= "Linux-$(KERNELRELEASE)"
scripts/Makefile.lib:                   -n "$(UIMAGE_NAME)" -d $< $@
scripts/Makefile.lib:                   --name "$(UIMAGE_NAME)" \


You quoted the definition of UIMAGE_NAME,
and also variable references.




See how it is expanded.


--name "$(UIMAGE_NAME)"


 ==>


--name ""Linux-$(KERNELRELEASE)""


 ==>


--name Linux-$(KERNELRELEASE)




You added double quotes in a row, just to cancel it.
