Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is an assorted set of stragglers into the merge window with
driver updates for qla2xxx, megaraid_sas, storvsc and ufs.
It also includes pulls of the uapi tree (all the remaining SCSI
pieces) and the fcoe tree (updates to fcoe and libfc)"
