Hi, This patchset cleans up 9 scsi drivers, ipr, ibmvscsi, fusion, aic7xxx, qla2xxx, lpfc, aacraid, BusLogic and aic79xxx. - remove the now unnecessary map_single path. - convert to new accessors for the scsi data buffer, the sg lists, bufferlen, resid. There are two patches for each driver, removing the non-use-sg code and converting to use the accessors. You can find the new accessors in the first patch. It includes scsi_dma_map/unmap (calling dma_map/unmap_sg) that Christoph proposed long ago and several macros (like scsi_for_each_sg, scsi_bufflen, etc) to isolate the driver from the sg lists and the parameters. This is in preparation for chaining sg lists and bidirectional requests and possibly the mid-layer dma mapping, which has been discussed. scsi_for_each_sg will be converted to use Jens' chaining sg lists (for_each_sg) when it's ready. Jens, sorry about overlapping with the chaining sg lists patches for the SCSI drivers. I tested the patches lightly, booting machines and performing some I/Os for few minutes. This patchset can be applied cleanly to the scsi-misc or Linus' tree. If this looks ok, I try to clean up the rest of the drivers (though I can only do compile tests). - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
