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 (10):
reservation keys, initiating and releasing reservations,
as well as clearing and preempting reservations held by
other keys.
These commands are crucial for management and control of
shared storage resources in a persistent manner.

Add persistent reservation in/out operations for raw driver.
The following methods are implemented: bdrv_co_pr_read_keys,
