Pull SCSI fixes from James Bottomley: "Three small bug fixes (barrier elimination, memory leak on unload, spinlock recursion) and a technical enhancement left over from the merge window: the TCMU read length support is required for tape devices read when the length of the read is greater than the tape block size" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: scsi_debug: Fix memory leak on module unload scsi: qla2xxx: Spinlock recursion in qla_target scsi: ipr: Eliminate duplicate barriers scsi: target: tcmu: add read length support
