Thanks -- this works well here. One suggestion would be to move the test file into lib/tests/ -- this is where we're keeping most of the KUnit tests for lib/ in order to avoid cluttering up lib/ and to make it possible to tab complete all of lib/glob.c. (Since the old file already started with lib/glob, this wouldn't be a regression, though, so if there's a particularly good reason to keep it there, it'd be okay. But otherwise, putting it in lib/tests/ would be best.) With that changed, this is: Reviewed-by: David Gow <[email protected]> Cheers, -- David > arch/m68k/configs/amiga_defconfig | 1 - > arch/m68k/configs/apollo_defconfig | 1 - > arch/m68k/configs/atari_defconfig | 1 - > arch/m68k/configs/bvme6000_defconfig | 1 - > arch/m68k/configs/hp300_defconfig | 1 - > arch/m68k/configs/mac_defconfig | 1 - > arch/m68k/configs/multi_defconfig | 1 - > arch/m68k/configs/mvme147_defconfig | 1 - > arch/m68k/configs/mvme16x_defconfig | 1 - > arch/m68k/configs/q40_defconfig | 1 - > arch/m68k/configs/sun3_defconfig | 1 - > arch/m68k/configs/sun3x_defconfig | 1 - > lib/Kconfig | 13 --- > lib/Kconfig.debug | 13 +++ > lib/Makefile | 2 +- > lib/glob_kunit.c | 122 +++++++++++++++++++ > lib/globtest.c | 167 --------------------------- > 17 files changed, 136 insertions(+), 193 deletions(-) > create mode 100644 lib/glob_kunit.c > delete mode 100644 lib/globtest.c > > diff --git a/arch/m68k/configs/amiga_defconfig > b/arch/m68k/configs/amiga_defconfig > index bfc1ee7c8..b51e22dea 100644 > --- a/arch/m68k/configs/amiga_defconfig > +++ b/arch/m68k/configs/amiga_defconfig > @@ -600,7 +600,6 @@ CONFIG_CRYPTO_USER_API_AEAD=m > CONFIG_PRIME_NUMBERS=m > CONFIG_CRC_BENCHMARK=y > CONFIG_XZ_DEC_TEST=m > -CONFIG_GLOB_SELFTEST=m > #
