tmscsim: replace by am53c974 driver

2014-11-24T15:13:18+00:00

The am53c974 is a re-implementation of the tmscsim driver, and provides the same functionality. So remove the tmscsim driver and make am53c974 an alias to tmscsim. Acked-by: Guennadi Liakhovetski Signed-off-by: Hannes Reinecke Signed-off-by: Christoph Hellwig

scsi: drop reason argument from ->change_queue_depth

2014-11-24T13:45:27+00:00

Drop the now unused reason argument from the ->change_queue_depth method. Also add a return value to scsi_adjust_queue_depth, and rename it to scsi_change_queue_depth now that it can be used as the default ->change_queue_depth implementation.

scsi: don't set tagging state from scsi_adjust_queue_depth

2014-11-12T10:19:43+00:00

Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

scsi: always assign block layer tags if enabled

2014-11-12T10:19:43+00:00

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.

scsi: remove abuses of scsi_populate_tag

2014-11-12T10:19:41+00:00

Unless we want to build a SPI tag message we should just check SCMD_TAGGED instead of reverse engineering a tag type through the use of scsi_populate_tag_msg. Also rename the function to spi_populate_tag_msg, make it behave like the other spi message helpers, and move it to the spi transport class.

scsi: use 64-bit LUNs

2014-07-17T20:07:37+00:00

The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.

[SCSI] tmscsim: Move 'last_reset' into host structure

SCSI: remove unnecessary pci_set_drvdata()

2013-10-14T13:26:04+00:00

Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Cc: James Bottomley Signed-off-by: Jiri Kosina

Drivers: scsi: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Cc: Adam Radford Cc: "James E.J.
