I'm looking into it now. Let me see if I can reproduce this on any of my hardware. If not there are a couple of options ... one is to only enable for ZBC devices where this explicitly required by the spec. Or disable for devices that report support trim?I'd much prefer enabling this only on ZBC devices. There isn't any real benefits to !ZBC devices, right? Using non-essential features on ATA never goes well.
Sure I'm fine with that. I'll move the WRITE SAME support to be conditional on ZBC. Sending a patch as soon as it's tested.
