Hi,

Please ignore the v2 series. Please review the v3 series instead.
Thanks!

v2->v3:
In v2 Persist Through Power Loss(PTPL) is enable default.
In v3 PTPL is supported, which is passed as a parameter.

v1->v2:
- Add sg_persist --report-capabilities for SCSI protocol and enable
  oncs and rescap for NVMe protocol.
- Add persistent reservation capabilities constants and helper functions for
  SCSI and NVMe protocol.
- Add comments for necessary APIs.

v1:
- Add seven APIs about persistent reservation command for block layer.
  These APIs including reading keys, reading reservations, registering,
  reserving, releasing, clearing and preempting.
- Add the necessary pr-related operation APIs for both the
  SCSI protocol and NVMe protocol at the device layer.
- Add scsi driver at the driver layer to verify the functions.
Changqi Lu (11):
  block: add persistent reservation in/out api
  block/raw: add persistent reservation in/out driver
  scsi/constant: add persistent reservation in/out protocol constants
  scsi/util: add helper functions for persistent reservation types
    conversion
  hw/scsi: add persistent reservation in/out api for scsi device
  block/nvme: add reservation command protocol constants
  hw/nvme: add helper functions for converting reservation types
  hw/nvme: enable ONCS reservations
  hw/nvme: enable namespace rescap function
  hw/nvme: add reservation protocal command
  block/iscsi: add persistent reservation in/out driver
