* Other types of errors that are detected immediately may be

* invoking the 'done' callback, and then returning 0 from this

* LLD is starting (or will start) the given command) then this
* function should place 0 in scp->result and return 0.

* immediately (and the LLD is starting (or will start) the given
* command) then this function should place 0 in scp->result and

*
* Command ownership. If the driver returns zero, it owns the
* command and must take responsibility for ensuring the 'done'
* callback is executed. Note: the driver may call done before
* returning zero, but after it has called done, it may not
* return any value other than zero. If the driver makes a
* non-zero return, it must not execute the command's done
* callback at any time.

*
* Locks: struct Scsi_Host::host_lock held on entry (with "irqsave")
* and is expected to be held on return.
* Locks: up to and including 2.6.36, struct Scsi_Host::host_lock
* held on entry (with "irqsave") and is expected to be
* held on return. From 2.6.37 onwards, queuecommand is
* called without any locks held.
*
* Calling context: in interrupt (soft irq) or process context
*
* Notes: This function should be relatively fast. Normally it will
* not wait for IO to complete. Hence the 'done' callback is invoked
* (often directly from an interrupt service routine) some time after
* this function has returned. In some cases (e.g. pseudo adapter
* drivers that manufacture the response to a SCSI INQUIRY)
* the 'done' callback may be invoked before this function returns.
* If the 'done' callback is not invoked within a certain period
* the SCSI mid level will commence error processing.
* If a status of CHECK CONDITION is placed in "result" when the
* 'done' callback is invoked, then the LLD driver should
* perform autosense and fill in the struct scsi_cmnd::sense_buffer
