It fixes the following: ./include/linux/kasan-enabled.h:9:1: warning: data definition has no type or storage class 9 | DECLARE_STATIC_KEY_FALSE(kasan_flag_enabled); | ^~~~~~~~~~~~~~~~~~~~~~~~ error: type defaults to 'int' in declaration of 'DECLARE_STATIC_KEY_FALSE' [-Werror=implicit-int] Fixes: f9b5e46f4097eb29 ("kasan: split kasan_*enabled() functions into a separate header") Cc: Peter Collingbourne <pcc@google.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> Acked-by: Andrey Konovalov <andreyknvl@gmail.com> Signed-off-by: Joey Gouly <joey.gouly@arm.com> Link: https://lore.kernel.org/r/20220301154518.19456-1-joey.gouly@arm.com Signed-off-by: Will Deacon <will@kernel.org> 2022-02-22T21:48:44+00:00 Peter Collingbourne pcc@google.com 2022-02-19T01:29:44+00:00 urn:sha1:f9b5e46f4097eb298f68e5b02f70697a90a44739 In an upcoming commit we are going to need to call kasan_hw_tags_enabled() from arch/arm64/include/asm/mte.h. This would create a circular dependency between headers if KASAN_GENERIC or KASAN_SW_TAGS is enabled: linux/kasan.h -> linux/pgtable.h -> asm/pgtable.h -> asm/mte.h -> linux/kasan.h. Break the cycle by introducing a new header linux/kasan-enabled.h with the kasan_*enabled() functions that can be included from asm/mte.h.
