Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger: - fix tcm-user backend driver expired cmd time processing (agrover) - eliminate kref_put_spinlock_irqsave() for I/O completion (bart) - fix iscsi login kthread failure case hung task regression (nab) - fix COMPARE_AND_WRITE completion use-after-free race (nab) - fix COMPARE_AND_WRITE with SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC non zero SGL offset data corruption. (Jan + Doug) - fix >= v4.4-rc1 regression for tcm_qla2xxx enable configfs attribute (Himanshu + HCH) * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target/stat: print full t10_wwn.model buffer target: fix COMPARE_AND_WRITE non zero SGL offset data corruption qla2xxx: Fix regression introduced by target configFS changes kref: Remove kref_put_spinlock_irqsave() target: Invoke release_cmd() callback without holding a spinlock target: Fix race for SCF_COMPARE_AND_WRITE_POST checking iscsi-target: Fix rx_login_comp hang after login failure iscsi-target: return -ENOMEM instead of -1 in case of failed kmalloc() target/user: Do not set unused fields in tcmu_ops target/user: Fix time calc in expired cmd processing
