The only other use case brought up is allowing use of vendor-specific commands while burning CDs. Given that the usual burning has been working well enough for years now, I don't really think that's a strong enough reason to add full BPF filtering to SG_IO. It's just highly unusual thing to do and there isn't strong enough use case for it.
To me, it feels like you guys are pushing a feature without strong enough use case. So, I'm still pretty strongly against it.
Thanks.
