From: Keith Busch <kbusch@xxxxxxxxxx> Changes from v7: Limits io_uring per-io hints to raw block, and only if the block device registers a new queue limit indicating support for it. The per-io hints are opaque to the kernel. Minor changelog and code organization changes. I don't really understand the io_uring suggestions, so I just made the write_hint a first class field without the "meta" indirection. It's kind of like ioprio, which has it's own field too. Actually, might be neat if we could use ioprio since it already has a "hints" field that is currently only used by command duration limits.
