I actually had a file backend implemented to benchmark it against the loopback driver. It needed absolutely zero new configfs interface.

PR APTPL immediately comes to mind. PRs are a useful feature on the road map. However we need a separate pluggable backend anyway for distributed backends like RBD or Bart's DLM implementation. Also the current LIO PR implementation will need a lot of work to be usable for NVMe while actually following the spec in all it's details and to be power ѕafe. The right way to go here is a PR API that allows different backends, and the existing LIO one might be one of them after it's got the needed attention. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
