From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi Jens, HCH & Co, This series introduces target_iostate and target_iomem descriptors that abstract what existing target backend drivers require in order to process I/O, sync_cache, write_same and unmap via sbc_ops. The purpose is to allow existing target backend drivers from within /sys/kernel/config/target/core/ to be accessed externally outside of the existing /sys/kernel/config/target/$FABRIC/ configfs layout, to operate independently of se_cmd and SCSI specific dependencies. Namely, it's intended for the upcoming nvme-target code to utilize existing target-core backend drivers and T10-PI logic, without requiring consumers to be under /sys/kernel/config/target/$FABRIC/ configfs layout. Also included is a prerequisite bug-fix for target-core, and IBLOCK optimization for eliminating the internal memory allocation. Beyond that, it's predominantly mechanical changes.
