* scsi: remove eh_timed_out methods in the transport templateChristoph Hellwig2017-02-0633-33/+38
| | | | | | | | | | | | | Instead define the timeout behavior purely based on the host_template eh_timed_out method and wire up the existing transport implementations in the host templates. This also clears up the confusion that the transport template method overrides the host template one, so some drivers have to re-override the transport template one.

| | | | | | | | | | | | | | | | | | Moved the READ and WRITE switch cases to the top. Added a default case to the switch case and replaced duplicate scsi result value with a macro. The idea is that since most of scsi commands we care about performance wise are read or write, we need to process them first. Internally the compiler (GCC) converts a switch case into either a jump table or a bunch of if else conditions, so placing the often used read, write cases at the top is an effort in optimization.

Due existence of loop in the IO path our HBA will receive heavy IOs and also as driver is not updating the Reply Post Host Index frequently, So there will be a high chance that our Firmware unable to find any free entry in the Reply Post Descriptor Queue (i.e. Queue overflow occurs) and can observe 0x2100 firmware fault. So to fix this, we have defined a thresh hold value. After continuously processing this thresh hold number of reply descriptors driver will update the Reply Descriptor Host Index so that this thresh hold number of reply descriptors entries will be freed and these entries will be available for firmware and we won't observe this Firmware fault. We have defined this threshold value as 1/3rd of the hba queue depth.

| | | | | | | | | | | | | | | | The v2 SAS controller needs more time to detect channel idle and send setup link request than SATA disk does, so it is difficult for the SAS controller to setup an STP link. Therefore it may cause some IO timeouts. We need to periodically configure the SAS controller so it doesn't receive STP setup requests from SATA disks for a while, so IO can be sent during this period.

* scsi: lpfc: Fix lpfc_wwn_set return code checkJames Smart2017-01-201-2/+2
| | | | | | | | | | | | | When I reversed the patch to re-add the lpfc_soft_wwn parameter feature, it re-added code that had a long-standing bug. (that's what I get I guess :) As Dan Carpenter pointed out - error checks looked at wrong polarity. 0 is success, -errno is failure. Updated checks.

* scsi: sd: Cleaned up comment references to @sdp argument explanation.John Pittman2017-01-201-2/+2
| | | | | | | | | | | | In sd.c there are two comment references to 'struct scsi_device *sdp' as an argument. One of the references has a typo and the other should be a reference to 'struct device *dev' instead. Fixed by correcting the typo in the first and changing the explanation in the second.
