Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "The patch set is mostly driver updates (bnx2fc, ipr, lpfc, qla4) and a few bug fixes" Pull delayed because google hates James, and sneakily considers his pull requests spam. Why, google, why? * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (60 commits) [SCSI] aacraid: 1024 max outstanding command support for Series 7 and above [SCSI] bnx2fc: adjust duplicate test [SCSI] qla4xxx: Update driver version to 5.03.00-k4 [SCSI] qla4xxx: Fix return code for qla4xxx_session_get_param.
