Hi Vincenzo,

Up till now, the code assumes that not having the async mode enabled
means that the sync mode is enabled. There are two callers to
kasan_async_mode_enabled(): lib/test_kasan.c and mm/kasan/report.c.
Assuming tests support will be added later, at least the second one
should be adjusted.

Maybe we should rename kasan_async_mode_enabled() to
kasan_async_fault_possible(), make it return true for both async and
asymm modes, and use that in mm/kasan/report.c. And also add
kasan_sync_fault_possible() returning true for sync and asymm, and use
that in lib/test_kasan.c. (However, it seems that the tests don't work
with async faults right now.)

It is ok by me, I will add the changes you are mentioning in v2.

Thanks!
