Cover letter [PATCH 0/5] cache request_queue pointer
Cache request_queue in bdev and replace two derefs in bdev->bd_disk->queue with bdev->bd_queue. Benchmarking with nullblk gave me around +1% to peak perf.
All patches are self contained and don't rely on others from the set including 1/5 and can be taken separately. And some changes go in separate patches to minimise conflicts. When we agree on the approach, I'll send the rest converting some other spots out of block.
note: based on for-5.16/block-io_uring
