| * scsi: remove ->change_queue_type methodChristoph Hellwig2014-12-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Since we got rid of ordered tag support in 2010 the prime use case of switching on and off ordered tags has been obsolete. The other function of enabling/disabling tagging entirely has only been correctly implemented by the 53c700 driver and isn't generally useful.

* | libsas: remove task_collector modeChristoph Hellwig2014-11-273-21/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The task_collector mode (or "latency_injector", (C) Dan Willians) is an optional I/O path in libsas that queues up scsi commands instead of directly sending it to the hardware. It generall increases latencies to in the optiomal case slightly reduce mmio traffic to the hardware. Only the obsolete aic94xx driver and the mvsas driver allowed to use it without recompiling the kernel, and most drivers didn't support it at all. Remove the giant blob of code to allow better optimizations for scsi-mq in the future.

* | scsi: avoid ->change_queue_depth indirection for queue full trackingChristoph Hellwig2014-11-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All drivers use the implementation for ramping the queue up and down, so instead of overloading the change_queue_depth method call the implementation diretly if the driver opts into it by setting the track_queue_depth flag in the host template. Note that a few drivers validated the new queue depth in their change_queue_depth method, but as we never go over the queue depth set during slave_configure or the sysfs file this isn't nessecary and can safely be removed.

|/ | | | | | | | | | | | | Allow a driver to ask for block layer tags by setting .use_blk_tags in the host template, in which case it will always see a valid value in request->tag, similar to the behavior when using blk-mq. This means even SCSI "untagged" commands will now have a tag, which is especially useful when using a host-wide tag map.

For calling task_done there is no need to enable the irq. So instead of using spin_lock_irqsave and spin_unlock_irqrestore, spin_lock and spin_unlock is used now.
