Subject: blk-mq: export blk_mq_map_queues
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9e5a7e22951bc12ee45cb617919d57b5efce56b5;p=linux-beck.git

blk-mq: export blk_mq_map_queues

This will allow SCSI to have a single blk_mq_ops structure that either
lets the LLDD map the queues to PCIe MSIx vectors or use the default.
