During patch review for an addition of archrandom.h for arm64, it was suggeted that the arch_random_get_* functions should be marked __must_check. Which does sound like a good idea, since the by-reference integer output may be uninitialized when the boolean result is false. In addition, I noticed a few other minor inconsistencies between the different architectures: x86 defines some functional macros outside CONFIG_ARCH_RANDOM, and powerpc isn't using bool. r~ Richard Henderson (6): random: Mark CONFIG_ARCH_RANDOM functions __must_check x86: Move arch_has_random* inside CONFIG_ARCH_RANDOM x86: Mark archrandom.h functions __must_check powerpc: Use bool in archrandom.h powerpc: Mark archrandom.h functions __must_check s390x: Mark archrandom.h functions __must_check arch/powerpc/include/asm/archrandom.h | 24 +++++++++++++----------- arch/s390/include/asm/archrandom.h | 8 ++++---- arch/x86/include/asm/archrandom.h | 24 ++++++++++++------------ include/linux/random.h | 8 ++++---- 4 files changed, 33 insertions(+), 31 deletions(-) -- 2.17.1
