One is by Yang Shi who added a READ_ONCE_NOCHECK() to the scan of the stack made by the stack tracer. As the stack tracer scans the entire kernel stack, KASAN triggers seeing it as a "stack out of bounds" error. As the scan is looking at the contents of the stack from parent functions. The NOCHECK() tells KASAN that this is done on purpose, and is not some kind of stack overflow. The second fix is to the ftrace selftests, to retrieve the PID of executed commands from the shell with "$!" and not by parsing "jobs".
