scripts/findconf provides menuconfig's search functionality as a

quick overview of symbol dependencies or determining which Kconfig

interactive config programs.
It accepts a single command-line flag, '-v', which causes it to also
print the help text of each matching result.

I can see how this could be useful.
It's a little easier to use than what I currently do:
$ findconfig DRM_HISI_HIBMC
./drivers/gpu/drm/hisilicon/hibmc/Kconfig:2:config DRM_HISI_HIBMC
I'm guessing 'findconfig' here is some personal shell
alias/function/script? (I can't see any references to it in the kernel
source tree.)
Yes, it's just local.
then $EDITOR that_Kconfig_file
In testing, I am seeing this:
#
# using defaults found in /boot/config-5.3.18-150300.59.63-default
#
.config:421:warning: symbol value 'm' invalid for I8K

.config:9653:warning: symbol value '1' invalid for KASAN_STACK
This I assume is just due to the contents of your .config file relative
to the current Kconfig definitions and not a problem with anything in
this patch?
There is no .config file in the linux/ source tree at the top level.
I use O=build_dir for all builds.
How do I specify/choose a .config file to be used?
Oh, use KCONFIG_CONFIG=filename
Ah, I guess that'd be a nice thing to add a flag for to the wrapper
script -- I'll include that in v2.
Please update (add) usage/help text in scripts/kconfig/Makefile.
Ack, will do.
Thanks for the review!
