Keith Busch 54bdd67d0f blk-mq: remove hybrid polling ... io_uring provides the only way user space can poll completions, and that always sets BLK_POLL_NOSLEEP. This effectively makes hybrid polling dead code, so remove it and everything supporting it. Hybrid polling was effectively killed off with 9650b453a3, "block: ignore RWF_HIPRI hint for sync dio", but still potentially reachable through io_uring until d729cf9acb, "io_uring: don't sleep when polling for I/O", but hybrid polling probably should not have been reachable through that async interface from the beginning. Fixes: 9650b453a3 ("block: ignore RWF_HIPRI hint for sync dio") Fixes: d729cf9acb ("io_uring: don't sleep when polling for I/O") Signed-off-by: Keith Busch <kbusch@kernel.org> Link: https://lore.kernel.org/r/20230320194926.3353144-1-kbusch@meta.com Signed-off-by: Jens Axboe <axboe@kernel.dk>		2023-03-20 15:30:03 -06:00
