Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley: "The vfs has long had a write lifetime hint mechanism that gives the expected longevity on storage of the data being written. f2fs was the original consumer of this and used the hint for flash data placement (mostly to avoid write amplification by placing objects with similar lifetimes in the same erase block). More recently the SCSI based UFS (Universal Flash Storage) drivers have wanted to take advantage of this as well, for the same reasons as f2fs, necessitating plumbing the write hints through the block layer and then adding it to the SCSI core. The vfs write_hints already taken plumbs this as far as block and this completes the SCSI core enabling based on a recently agreed reuse of the old write command group number. The additions to the scsi_debug driver are for emulating this property so we can run tests on it in the absence of an actual UFS device" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: scsi_debug: Maintain write statistics per group number scsi: scsi_debug: Implement GET STREAM STATUS scsi: scsi_debug: Implement the IO Advice Hints Grouping mode page scsi: scsi_debug: Allocate the MODE SENSE response from the heap scsi: scsi_debug: Rework subpage code error handling scsi: scsi_debug: Rework page code error handling scsi: scsi_debug: Support the block limits extension VPD page scsi: scsi_debug: Reduce code duplication scsi: sd: Translate data lifetime information scsi: scsi_proto: Add structures and constants related to I/O groups and streams scsi: core: Query the Block Limits Extension VPD page
