Stefan, the issue you mentioned has been fixed. Almost all patches have
been reviewed, thank you very much to Stefan and Klaus. v7->v8: - Fix
num_keys may be less than 0 at scsi_pr_read_keys_complete(). - Fix buf
memory leak at iscsi driver. v6->v7: - Add buferlen size check at SCSI
layer. - Add pr_cap calculation in bdrv_merge_limits() function at block
layer, so the ugly bs->file->bs->bl.pr_cap in scsi and nvme layers was
changed to bs->bl.pr_cap. - Fix memory leak at iscsi driver, and some other
spelling errors. v5->v6: - Add relevant comments in the io layer. v4->v5: -
Fixed a memory leak bug at hw/nvme/ctrl.c. v3->v4: - At the nvme layer, the
two patches of enabling the ONCS function and enabling rescap are combined
into one. - At the nvme layer, add helper functions for pr capacity
conversion between the block layer and the nvme layer. 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 (10): 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

reservation command protocol constants hw/nvme: add helper functions for
converting reservation types hw/nvme: enable ONCS and rescap function
