Merge branch 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
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. Kudos to Hannes for driving SMR support" * 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (28 commits) libata: support host-aware and host-managed ZAC devices libata: support device-managed ZAC devices libata: NCQ encapsulation for ZAC MANAGEMENT OUT libata: Implement ZBC OUT translation libata: implement ZBC IN translation libata: fixup ZAC device disabling libata-scsi: Generate sense code for disabled devices libata-trace: decode subcommands libata: Check log page directory before accessing pages libata: Add command definitions for NCQ Encapsulation for READ LOG DMA EXT libata: Separate out ata_dev_config_ncq_send_recv() libata/libsas: Define ATA_CMD_NCQ_NON_DATA libsas: enable FPDMA SEND/RECEIVE libata: do not attempt to retrieve sense code twice libata-scsi: Set information sense field for invalid parameter libata-scsi: set bit pointer for sense code information libata-scsi: Set field pointer in sense code scsi: add scsi_set_sense_field_pointer() libata: Implement control mode page to select sense format libata-scsi: generate correct ATA pass-through sense ...
