Tejun, I need a way to limit the multi_count to a specific maximum value for sata_mv. ISTR that some PATA chips may also have an upper hardware limit on multi_count. Generally, "8" is safe for all chipsets. Going above that requires knowledge of what the chipset can tolerate. How about a u8 multi_count_max field in the ata_host struct? Use 0xff for "multi_count not allowed", and anything else in there as an upper limit for the chipset. ??? -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
