Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "The most notable item is IBM virtual SCSI target driver, that was originally ported to target-core back in 2010 by Tomo-san, and has been brought forward to v4.x code by Bryant Ly, Michael Cyr and co over the last months. Also included are two ORDERED task related bug-fixes Bryant + Michael found along the way using ibmvscsis with AIX guests, plus a few miscellaneous target-core + iscsi-target bug-fixes with associated stable tags" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: fix spelling mistake: "limitiation" -> "limitation" target: Fix residual overflow handling in target_complete_cmd_with_length tcm_fc: set and unset FCP_SPPF_TARG_FCN iscsi-target: Fix panic when adding second TCP connection to iSCSI session ibmvscsis: Initial commit of IBM VSCSI Tgt Driver target: Fix ordered task CHECK_CONDITION early exception handling target: Fix ordered task target_setup_cmd_from_cdb exception hang target: Fix max_unmap_lba_count calc overflow target: Fix race between iscsi-target connection shutdown + ABORT_TASK target: Fix missing complete during ABORT_TASK + CMD_T_FABRIC_STOP
