Subject: [PATCH rebase v2] kunit: add --make_options
From: Greg Thelen <gthelen@...gle.com>
The kunit.py utility builds an ARCH=um kernel and then runs it. Add
optional --make_options flag to kunit.py allowing for the operator to
specify extra build options.
This allows use of the clang compiler for kunit:
tools/testing/kunit/kunit.py run --defconfig \
--make_options CC=clang --make_options HOSTCC=clang
