Merge branch 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2016-05-24T00:53:39Z

Pull libata ZAC support from Tejun Heo: "This contains Zone ATA Command support for Shingled Magnetic Recording devices. In addition to sending the new commands down to the device, as ZAC commands depend on getting a lot of responses from the device, piping up responses is beefed up too. However, it doesn't involve changes to libata core mechanism or its interaction with upper layers, so I'm not expecting too many fallouts.

libata: support host-aware and host-managed ZAC devices

2016-05-09T16:36:46Z

Byte 69 bits 0:1 in the IDENTIFY DEVICE data indicate a host-aware ZAC device. Host-managed ZAC devices have their own individual signature, and to not set the bits in the IDENTIFY DEVICE data. And whenever we detect a ZAC-compatible device we should be displaying the zoned block characteristics VPD page. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: support device-managed ZAC devices

2016-05-09T16:36:46Z

Device-managed ZAC devices just set the zoned capabilities field in INQUIRY byte 69 (cf ACS-4). This corresponds to the 'zoned' field in the block device characteristics VPD page. As this is only defined in SPC-5/SBC-4 we also need to update the supported SCSI version descriptor.

libata: NCQ encapsulation for ZAC MANAGEMENT OUT

2016-05-09T16:36:46Z

Add NCQ encapsulation for ZAC MANAGEMENT OUT and evaluate NCQ Non-Data log pages to figure out if NCQ encapsulation is supported. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Implement ZBC OUT translation

2016-05-09T16:36:46Z

ZAC drives implement a 'ZAC Management Out' command template, which maps onto the ZBC OUT command. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: implement ZBC IN translation

ZAC drives implement a 'ZAC Management In' command template, which maps onto the ZBC IN command. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata-scsi: Generate sense code for disabled devices

2016-05-09T16:36:45Z

If a device is disabled after error recovery it doesn't make any sense to generate an ATA sense, but we should rather return a generic sense code indicating the device is gone. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata-scsi: Set information sense field for invalid parameter

2016-04-04T16:07:42Z

Whenever the sense key is set to 'invalid parameter' we should be filling out the sense-key specific information field in the sense buffer. tj: Added description of @fp for ata_mselect_*(). Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo
