177  如果Operations with implied preemption/interrupt protection. These* operations can be used without worrying about preemption or interrupt.(CMCI storm detection backoff counter* During storm, we reset this counter to INITIAL_CHECK_INTERVAL in case we've* encountered an error. If not, we decrement it by one. We signal the end of* the CMCI storm when it reaches 0.)大于0且Operations for contexts that are safe from preemption/interrupts. These* operations verify that preemption is disabled.(cmci_storm_state)恒等于CMCI_STORM_ACTIVE则
