The first 5 patches move the magic IDE request types into the old IDE driver to keep the core block code clean of them. Those are basically ready to merge, just like the 6th one which is a cleanup on it's own. The real RFC is the last one which allocates the block_pc specific data separately in the callers instead of bloating every struct request with it. I always hated what we did, but with the upcoming split of nvme into transports and command sets we'll need a NVME equivalent of BLOCK_PC, and as NVMe was designed by crackmonkeys dreaming of an ATA controller the "command block" for NVME is even bigger than what we have to deal with in SCSI. Note that the old IDE driver doesn't compile with the last patch yet as there are major nightmares to sort out, and BLOCK_PC passthrough with dm-multipath doesn't work yet either. If I get some general concensus on the approach I'll fix those of course. -- 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
