blk-mq-rdma: remove queue mapping helper for rdma devices

2023-04-13T06:59:05Z

No rdma device exposes its irq vectors affinity today. So the only mapping that we have left, is the default blk_mq_map_queues, which we fallback to anyways. Also fixup the only consumer of this helper (nvme-rdma). Remove this now dead code. Signed-off-by: Sagi Grimberg Acked-by: Keith Busch Signed-off-by: Christoph Hellwig

block: Change the return type of blk_mq_map_queues() into void

2022-08-22T16:07:53Z

Since blk_mq_map_queues() and the .map_queues() callbacks always return 0, change their return type into void. Most callers ignore the returned value anyway.

block: Add rdma affinity based queue mapping helper

2017-08-08T18:58:03Z

Like pci and virtio, we add a rdma helper for affinity spreading. This achieves optimal mq affinity assignments according to the underlying rdma device affinity maps.
