You don't know, and nobody knows, a simple solution that can apply to my case:

  I'm not your exclusive reviewer, and I'm not familiar with the block layer.
  Actually, I'm not a developer living in block layer, and I'm not subscribed
  to linux-block mailing list. I check bugs reported by syzbot, and analyze
  and try to write patches. I can't afford monitoring patches of all mailing
  lists.

  In order words, I can't review your patches and can't provide detailed feedback
  (unless you cc me with detailed explanation of why it is safe to make such change).

Bugs are merged everywhere but I can't prevent bugs from getting merged. I monitor
bugs reported by syzbot. It is exactly like patches just appear in a tree somewhere.
