Hi, Is it possible to enable DISCARD support for snapshot-origin target? Currently it returns EOPNOTSUPP even if underlying device does support it. I know there are some cases when it isn't desirable (for example mkfs.ext4 discards the entire device, which would trigger copyout to the snapshot), but I can live with that. Or, if possible, better to prevent that copyout if discarded block(s) were zeroed already. Which would handle the case of mkfs.ext4 on empty, zeroed device. I see that it may undesired in some cases, so maybe some configurable option? Like module parameter or so? -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
