Hello Quinn, Are you perhaps referring to the 2015 LSF/MM session I had proposed ([LSF/MM TOPIC] Unifying the LIO and SCST target drivers - https://marc.info/?l=linux-scsi&m=142122995413575)? The approach taken in patch 08/22 of this series is not what I had in mind. More in general, as you maybe know shim (translation) layers are not welcome in the Linux kernel. Simplifying the LIO core is still on my to do list. A possible starting point is the patch series I posted one year ago ([PATCH 00/20] SCSI target patches for kernel v4.4 - https://www.spinics.net/lists/target-devel/msg10788.html). That kind of simplification helps with reducing the maintenance burden for target drivers that support the two in-kernel SCSI target stacks without violating any of the established rules for kernel driver development.
