Just spoke to Jerry, we'll be doing a 3.0.27a on Monday to fix a regression that broke smbfs mounts from Linux. Sorry for the problem. Jeremy.

This series tries to access virtqueue metadata through kernel virtual address instead of copy_user() friends since they had too much overheads like checks, spec barriers or even hardware feature toggling. This is done through setup kernel address through vmap() and resigter MMU notifier for invalidation. Test shows about 24% improvement on TX PPS. TCP_STREAM doesn't see obvious improvement.

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the

Very large but mechanical change to the generator. Rich.
