Pull SCSI target updates from Nicholas Bellinger:
 "The highlights this round include:

   - Add support for T10 PI pass-through between vhost-scsi +
     virtio-scsi (MST + Paolo + MKP + nab)
   - Add support for T10 PI in qla2xxx target mode (Quinn + MKP + hch +
     nab, merged through scsi.git)
   - Add support for percpu-ida pre-allocation in qla2xxx target code
     (Quinn + nab)
   - A number of iser-target fixes related to hardening the network
     portal shutdown path (Sagi + Slava)
   - Fix response length residual handling for a number of control CDBs
     (Roland + Christophe V.)
   - Various iscsi RFC conformance fixes in the CHAP authentication path
     (Tejas and Calsoft folks + nab)
   - Return TASK_SET_FULL status for tcm_fc(FCoE) DataIn + Response
     failures (Vasu + Jun + nab)
   - Fix long-standing ABORT_TASK + session reset hang (nab)
   - Convert iser-initiator + iser-target to include T10 bytes into EDTL
     (Sagi + Or + MKP + Mike Christie)
   - Fix NULL pointer dereference regression related to XCOPY introduced
     in v3.15 + CC'ed to v3.12.y (nab)"
