We've been reporting 2 maps regardless of whether the module parameter asked for anything beyond the default queues. A consequence of this means that blk-mq will reinitialize the all the hardware contexts and io schedulers on every controller reset when the mapping is exactly the same as before. This unnecessary overhead is adding several milliseconds on a reset for environments that don't need it. Report the actual number of mappings in use.
