Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "Two small fixes: one in drivers (qla2xxx), and one in the core (sd) to try to cope with USB enclosures that silently change reported parameters" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: sd: Fix optimal I/O size for devices that change reported values scsi: qla2xxx: Fix I/Os being passed down when FC device is being deleted
