The remaining five patches all try to fix commit 84676c1f21e8 ("genirq/affinity: assign vectors to all possible CPUs") which broke the non-mq I/O path" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: iscsi_tcp: set BDI_CAP_STABLE_WRITES when data digest enabled scsi: sd: Remember that READ CAPACITY(16) succeeded scsi: ibmvfc: Avoid unnecessary port relogin scsi: virtio_scsi: unify scsi_host_template scsi: virtio_scsi: fix IO hang caused by automatic irq vector affinity scsi: core: introduce force_blk_mq scsi: megaraid_sas: fix selection of reply queue scsi: hpsa: fix selection of reply queue
