Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This consists of the usual driver updates (ufs, qla2xxx, tcmu, lpfc,
hpsa, zfcp, scsi_debug) and minor bug fixes.
We also have a huge docbook fix update like most other subsystems and
no major update to the core (the few non trivial updates are either
minor fixes or removing an unused feature [scsi_sdb_cache])"
