blk-mq layer performs a remapping between s/w and h/w contexts and also between h/w contexts and CPUs, whenever a CPU hotplug event happens. This remapping has to wait for queue freezing which may take tens of miliseconds, resulting in a high latency in CPU hotplug path. This patch makes the above mentioned mappings static so that we can avoid remapping when CPU hotplug event happens and this results in improved CPU hotplug latency of up to 90 percent for CPU up path and of up to 50 percent for CPU down path.
