This patch converts the existing glob selftest (lib/globtest.c) to use the KUnit framework (lib/glob_kunit.c).
The new test:
- Migrates all 64 test cases from the original test to the KUnit suite. - Removes the custom 'verbose' module parameter as KUnit handles logging. - Updates Kconfig.debug and Makefile to support the new KUnit test. - Updates Kconfig and Makefile to remove the original selftest. - Updates GLOB_SELFTEST to GLOB_KUNIT_TEST for arch/m68k/configs.
This commit is verified by `./tools/testing/kunit/kunit.py run` with the .kunit/.kunitconfig:
``` CONFIG_KUNIT=y CONFIG_GLOB_KUNIT_TEST=y ```
