The functions blk_mq_sched_free_hctx_data(), blk_mq_sched_try_merge(), blk_mq_sched_try_insert_merge() and blk_mq_sched_request_inserted() are all exported symbols but declared only internally in block/blk-mq-sched.h. Move their declaration to include/linux/blk-mq.h to make them available to block external scheduler modules.
