PING: [PATCH v6 00/10] Support persistent reservation operations

[卢长奇]

Hi,

@Stefan, many thanks to you for reviewing the code.
@Klaus, the block layer code has been reviewed by Stefan.
Please help review the nvme layer code.
@Paolo, Please help review the scsi layer code and iscsi
driver code.
Thank you!
