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

2023-04-13T06:59:05+00:00

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

2022-08-22T16:07:53+00:00

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: Fix blk_mq_*_map_queues() kernel-doc headers

2019-05-31T21:12:34+00:00

This patch avoids that the kernel-doc script complains about these function headers when building with W=1.

block: switch all files cleared marked as GPLv2 to SPDX tags

2019-04-30T22:11:57+00:00

All these files have some form of the usual GPLv2 boilerplate. Switch them to use SPDX tags instead. Reviewed-by: Chaitanya Kulkarni Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

blk-mq: abstract out queue map

This is in preparation for allowing multiple sets of maps per queue, if so desired. Reviewed-by: Hannes Reinecke Reviewed-by: Bart Van Assche Reviewed-by: Keith Busch Signed-off-by: Jens Axboe

block: Add rdma affinity based queue mapping helper

2017-08-08T18:58:03+00:00

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.
