This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas, megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor updates. There's no major behaviour change or additions to the core in all of this, so the potential for regressions should be small (biggest potential being in the scsi error handler changes).
