Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "Here are the target pending updates for v3.15-rc1. Apologies in advance for waiting until the second to last day of the merge window to send these out. The highlights this round include: - iser-target support for T10 PI (DIF) offloads (Sagi + Or) - Fix Task Aborted Status (TAS) handling in target-core (Alex Leung) - Pass in transport supported PI at session initialization (Sagi + MKP + nab) - Add WRITE_INSERT + READ_STRIP T10 PI support in target-core (nab + Sagi) - Fix iscsi-target ERL=2 ASYNC_EVENT connection pointer bug (nab) - Fix tcm_fc use-after-free of ft_tpg (Andy Grover) - Use correct ib_sg_dma primitives in ib_isert (Mike Marciniszyn) Also, note the virtio-scsi + vhost-scsi changes to expose T10 PI metadata into KVM guest have been left-out for now, as there where a few comments from MST + Paolo that where not able to be addressed in time for v3.15. Please expect this feature for v3.16-rc1" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (43 commits) ib_srpt: Use correct ib_sg_dma primitives target/tcm_fc: Rename ft_tport_create to ft_tport_get target/tcm_fc: Rename ft_{add,del}_lport to {add,del}_wwn target/tcm_fc: Rename structs and list members for clarity target/tcm_fc: Limit to 1 TPG per wwn target/tcm_fc: Don't export ft_lport_list target/tcm_fc: Fix use-after-free of ft_tpg target: Add check to prevent Abort Task from aborting itself target: Enable READ_STRIP emulation in target_complete_ok_work target/sbc: Add sbc_dif_read_strip software emulation target: Enable WRITE_INSERT emulation in target_execute_cmd target/sbc: Add sbc_dif_generate software emulation target/sbc: Only expose PI read_cap16 bits when supported by fabric target/spc: Only expose PI mode page bits when supported by fabric target/spc: Only expose PI inquiry bits when supported by fabric target: Pass in transport supported PI at session initialization target/iblock: Fix double bioset_integrity_free bug Target/sbc: Initialize COMPARE_AND_WRITE write_sg scatterlist target/rd: T10-Dif: RAM disk is allocating more space than required. iscsi-target: Fix ERL=2 ASYNC_EVENT connection pointer bug ...
