Subject: [PATCH v2 4/5] kunit: assert_test: Prepare to be merged into kunit-test.c
Add 'kunit_assert_' prefix for 'is_literal' and 'is_str_literal'
functions. This way we will be sure that we are not exporting ambiguous
symbols into the KUnit namespace.
Export these (and other) functions from assert into the KUnit namespace,
so we could use them in the tests (and cover them as well).
Signed-off-by: Ivan Orlov <ivan.orlov0322@...il.com>
---
V1 -> V2:
- Besides exporting the non-static functions from assert.c into the
KUnit namespace, rename some of them as well (add kunit_assert_ prefix
to make their names less ambiguous).
