Anyway I just want to know whether we still need auto scale of poll rate or not.

We couldn't fix the warning with your patch. the patch below fixes it instead.
IMHO, gcc can't seems to k
t the default affinity to the boot cpu in gic_dist_init. thereafter,
irq_data->affinity will be set to default 1-bit affinity.
- Even if we write multiple bits to smp_affinity, both irq_data and gic
register will be set one cpu. procfs will show 1 bit affinity as well.

scsi_request_fn is called under the lock of request_queue->queue_lock.
If we drop the sdev reference to zero here,
scsi_device_dev_release_usercontext is
invoked and make request_queue to NULL. Wh
