There are three parts in this series: Firstly, at the block layer, the commit abstracts seven APIs related to the persistent reservation command. These APIs including reading keys, reading reservations, registering, reserving, releasing, clearing and preempting. Next, the commit implements the necessary pr-related operation APIs for both the SCSI protocol and NVMe protocol at the device layer. This ensures that the necessary functionality is available for handling persistent reservations in these protocols. Finally, the commit includes adaptations to the iscsi driver at the driver layer to verify the correct implementation and functionality of the changes. With these changes, GFS works fine in the guest. Also, sg-utils(for SCSI block) and nvme-cli(for NVMe block) work fine too.
