John, > Are you happy for us to make DIX support in this driver "hisi_sas DIX > experimental" short term? That's entirely your call, it's your driver/controller. I just want the experimental tag to be due to reasons on *your* end. If it's reasons on my end they'll need to get fixed. We shouldn't have drivers circumventing features because of bugs in the core block/SCSI code... -- Martin K. Petersen Oracle Linux Engineering
