Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "Things have been quiet this round with mostly bugfixes, percpu conversions, and other minor iscsi-target conformance testing changes. The highlights include: - Add demo_mode_discovery attribute for iscsi-target (Thomas) - Convert tcm_fc(FCoE) to use percpu-ida pre-allocation - Add send completion interrupt coalescing for ib_isert - Convert target-core to use percpu-refcounting for se_lun - Fix mutex_trylock usage bug in iscsit_increment_maxcmdsn - tcm_loop updates (Hannes) - target-core ALUA cleanups + prep for v3.14 SCSI Referrals support (Hannes) v3.14 is currently shaping to be a busy development cycle in target land, with initial support for T10 Referrals and T10 DIF currently on the roadmap" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (40 commits) iscsi-target: chap auth shouldn't match username with trailing garbage iscsi-target: fix extract_param to handle buffer length corner case iscsi-target: Expose default_erl as TPG attribute target_core_configfs: split up ALUA supported states target_core_alua: Make supported states configurable target_core_alua: Store supported ALUA states target_core_alua: Rename ALUA_ACCESS_STATE_OPTIMIZED target_core_alua: spellcheck target core: rename (ex,im)plict -> (ex,im)plicit percpu-refcount: Add percpu-refcount.o to obj-y iscsi-target: Do not reject non-immediate CmdSNs exceeding MaxCmdSN iscsi-target: Convert iscsi_session statistics to atomic_long_t target: Convert se_device statistics to atomic_long_t target: Fix delayed Task Aborted Status (TAS) handling bug iscsi-target: Reject unsupported multi PDU text command sequence ib_isert: Avoid duplicate iscsit_increment_maxcmdsn call iscsi-target: Fix mutex_trylock usage in iscsit_increment_maxcmdsn target: Core does not need blkdev.h target: Pass through I/O topology for block backstores iser-target: Avoid using FRMR for single dma entry requests ...
