The problem with interruptible sleeps of this nature is that they are no-ops if the calling process happens to have signal_pending(). I suspect that this condition will break your driver. If so, switching to schedule_timeout_uninterruptible() will unbreak it. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
