Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is mostly update of the usual drivers: smarpqi, lpfc, qedi,
megaraid_sas, libsas, zfcp, mpt3sas, hisi_sas.
Additionally, we have a pile of annotation, unused variable and minor
updates.
The big API change is the updates for Christoph's DMA rework which
include removing the DISABLE_CLUSTERING flag.
And finally there are a couple of target tree updates"
