Jan says "your change makes sense" at https://lkml.kernel.org/m/20210322153142.GF31783@quack2.suse.cz and Jeff says "Tetsuo's patch is fine" at https://lkml.kernel.org/m/7d7a884a-5a94-5b0e-3cf5-82d12e1b0992@suse.com and I'm waiting for Jan/Jeff's reply to "why you think that my patch is incomplete" at https://lkml.kernel.org/m/fa9f373a-a878-6551-abf1-903865a9d21f@i-love.sakura.ne.jp . Since Jan/Jeff seems to be busy, applying as-is will let syzkaller answer to my question.
