Subject: [PATCH 07/10] merge_config.sh: add tests
For being a small script, merge_config.sh is fairly scary to change since there's no
real way to know if you did something wrong. So it seems appropriate to add a simple
test suite.
I've started with testcases in the areas I care about, other should of course feel
free to expand on this.
Use is simple, from the kernel tree, run ./scripts/kconfig/merge_config_test/runall.
It'll execute out of a tmpdir under /tmp.
