Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This patch is the usual mix of driver updates (srp, ipr, scsi_debug, NCR5380, fnic, 53c974, ses, wd719x, hpsa, megaraid_sas). Of those, wd7a9x is new and 53c974 is a rewrite of the old tmscsim driver and the extensive work by Finn Thain rewrites all the NCR5380 based drivers. There's also extensive infrastructure updates: a new logging infrastructure for sense information and a rewrite of the tagged command queue API and an assortment of minor updates" * tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (183 commits) scsi: set fmt to NULL scsi_extd_sense_format() by default libsas: remove task_collector mode wd719x: remove dma_cache_sync call scsi_debug: add Report supported opcodes+tmfs; Compare and write scsi_debug: change SCSI command parser to table driven scsi_debug: add Capacity Changed Unit Attention scsi_debug: append inject error flags onto scsi_cmnd object scsi_debug: pinpoint invalid field in sense data wd719x: Add firmware documentation wd719x: Introduce Western Digital WD7193/7197/7296 PCI SCSI card driver eeprom-93cx6: Add (read-only) support for 8-bit mode esas2r: fix an oversight in setting return value esas2r: fix an error path in esas2r_ioctl_handler esas2r: fir error handling in do_fm_api scsi: add SPC-3 command definitions scsi: rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 scsi: remove scsi_driver owner field scsi: move scsi_dispatch_cmd to scsi_lib.c scsi: stop passing a gfp_mask argument down the command setup path scsi: remove scsi_next_command ...
