Generally, yes. The inline mode also might require adding some __no_sanitize_address annotations. Typically for lower-level function that get messed up by the inline instrumentation. But the annotations previously added for the Generic mode would work for SW_TAGS as well, unless SW_TAGS instrumentation touches some other low-level code. > Oh, I guess I also need to add a patch to handle the int3 (X86_TRAP_BP) so > kasan reports show up in inline mode. Ah, yes, for SW_TAGS, need an appropriate handler here.
