[PATCH v3 0/7] scsi: target: Add WRITE_ATOMIC_16 support

[John Garry <john.g.garry@oracle.com>]

This is a reposting of Mike's atomic writes support for the SCSI target.

Again, we are now only supporting target_core_iblock. It's implemented
similar to UNMAP where we do not do any emulation and instead pass the
operation to the block layer.

Changes since v2:
- Fix 32b build error

Changes since v1:
- Don't make atomic alignment configurable
- Drop atomic_supported configfs entry
- reformatting
- fix lba size in sbc_check_atomic()
- fix return code from sbc_check_atomic()

Mike Christie (7):
  scsi: target: Rename target_configure_unmap_from_queue
  scsi: target: Add atomic se_device fields
  scsi: target: Add helper to setup atomic values from block_device
  scsi: target: Add WRITE_ATOMIC_16 handler
  scsi: target: Report atomic values in INQUIRY
  scsi: target: Add WRITE_ATOMIC_16 support to RSOC
  scsi: target: Add atomic support to target_core_iblock
