Perhaps we could add a generic arch-agnostic enum to
include/linux/kasan.h and use it in both arm64 and KASAN code?
enum kasan_hw_tags_mode {
KASAN_HW_TAGS_SYNC,
KASAN_HW_TAGS_ASYNC
}
Assuming other architectures that support memory tagging will end up
with sync/async mode separation as well, this should work. But even if
that doesn't happen, this interface can be adjusted later.I am fine with this solution, I will add it in my v3. As part of the enumeration I will add READ_SYNC mode as well, so we have all the possible combinations. -- Regards, Vincenzo _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
