Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger: "Mostly minor items this time around, the most notable being a FILEIO backend change to enforce hw_max_sectors based upon the current block_size to address a bug where large sized I/Os (> 1M) where being rejected" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: qla2xxx: Fix scsi_host leak on qlt_lport_register callback failure target: Remove extra percpu_ref_init target/file: Update hw_max_sectors based on current block_size iser-target: Move INIT_WORK setup into isert_create_device_ib_res iscsi-target: Fix incorrect np->np_thread NULL assignment qla2xxx: Fix schedule_delayed_work() for target timeout calculations iser-target: fix error return code in isert_create_device_ib_res() iscsi-target: Fix-up all zero data-length CDBs with R/W_BIT set target: Remove write-only stats fields and lock from struct se_node_acl iscsi-target: return -EINVAL on oversized configfs parameter
