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: "This patch consists of the usual driver updates (megaraid_sas, scsi_debug, qla2xxx, qla4xxx, lpfc, bnx2fc, be2iscsi, hpsa, ipr) plus an assortment of minor fixes and the first precursors of SCSI-MQ (the code path simplifications) and the bug fix for the USB oops on remove (which involves an infrastructure change, so is sent via the main tree with a delayed backport after a cycle in which it is shown to introduce no new bugs)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (196 commits) [SCSI] sd: Quiesce mode sense error messages [SCSI] add support for per-host cmd pools [SCSI] simplify command allocation and freeing a bit [SCSI] megaraid: simplify internal command handling [SCSI] ses: Use vpd information from scsi_device [SCSI] Add EVPD page 0x83 and 0x80 to sysfs [SCSI] Return VPD page length in scsi_vpd_inquiry() [SCSI] scsi_sysfs: Implement 'is_visible' callback [SCSI] hpsa: update driver version to 3.4.4-1 [SCSI] hpsa: fix bad endif placement in RAID 5 mapper code [SCSI] qla2xxx: Fix build errors related to invalid print fields on some architectures. [SCSI] bfa: Replace large udelay() with mdelay() [SCSI] vmw_pvscsi: Some improvements in pvscsi driver. [SCSI] vmw_pvscsi: Add support for I/O requests coalescing. [SCSI] vmw_pvscsi: Fix pvscsi_abort() function. [SCSI] remove deprecated IRQF_DISABLED from SCSI [SCSI] bfa: Updating Maintainers email ids [SCSI] ipr: Add new CCIN definition for Grand Canyon support [SCSI] ipr: Format HCAM overlay ID 0x21 [SCSI] ipr: Use pci_enable_msi_range() and pci_enable_msix_range() ...
