You keep ignoring inconvenient facts. For about the third time: I run a test bed for sg_tables (large chaining of requests). This runs on parisc using virtual merging (has to because the final physical table size can't go over the sg list of the SCSI card). If I turn off virtual merging I can no longer test sg_tables in vanilla kernels.
