Description Andrey Konovalov 2021-03-09 15:46:37 UTC
As there are multiple KASAN modes that all work differently, it makes sense to mention the enabled mode in the "KernelAddressSanitizer initialized" message. Something like:

kasan: KernelAddressSanitizer initialized (generic)

kasan: KernelAddressSanitizer initialized (hw-tags, mode=async, stacktrace=on)
Comment 1 Andrey Konovalov 2021-11-14 21:27:03 UTC
Done for arm64 in [1]. Other arches only support the Generic mode, so having different messages doesn't apply.
