Well, I guess this goes with the context-less nvme patch. I think you're much better off just removing the bi_inline_vecs array entirely, and just add a new structure for bio + inline vecs for the few callers that dynamically allocate the bio and actually have inline vecs. Similar to what I did here for the bio integrity payload: https://lore.kernel.org/linux-block/20250131122436.1317268-4-hch@xxxxxx/
