The concurrently decrements of host_failed only lead to abnormal
of host_failed, host_busy will be zero after error handler, and
the result may be host_failed > host_busy forever. But in your
case, host_busy > host_failed, so I think it's not the same
case. I'm afraid that this patch can't fix your scsi hang issue.

Thanks,
Wei
