Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
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
