Same issue as reported previously. Copying my response from the other
email just in case:
This is the same issue in LLVM that was reported by Arnd for generic
KASAN (also see KASAN_STACK_ENABLE option description). By default
KASAN shouldn't have stack instrumentation enabled unless
KASAN_STACK_ENABLE is specified. Perhaps it makes sense to disable it
for KASAN_SW_TAGS config on the kernel test robot.

Hi Andrey,
Thanks for the explanation, we'll disable CONFIG_KASAN_SW_TAGS.

Hi Rong,
No, no, if you have a CONFIG_KASAN_SW_TAGS-based config - keep it
enabled, just disable CONFIG_KASAN_STACK_ENABLE to avoid these stack
overflows.
