Hi Jens,

It adds basic support for a harwdare based copy relation to the DASD

Hi Stefan,

How's the relation of this patchset to the current efforts of getting a common
copy offload API (NVMe Simple Copy and SCSI XCOPY) into the block-layer?


Thanks,

Hi Johannes,

there is no relation to this efforts.
My patchset basically aims to add some support of IBMs Peer-to-Peer-Remote-Copy (PPRC) hardware feature to the DASD device driver. PPRC is a protocol that might be used without any OS interaction on a storage server level. This patchset allows the driver to recognize such devices correctly and allows an user to make a copy relation known to the driver. In this case Linux is only an observer/user of the copy relation which is set up by an external entity.


regards,
Stefan
