Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI barrier fix from James Bottomley:
"This is a potential data corruption fix: If we get an error sending
down a barrier, we simply ignore it meaning the barrier semantics get
violated without anyone being any the wiser. If the system crashes at
this point, the filesystem potentially becomes corrupt. Fix is to
report errors on failed barriers"
