Pardon my cursory review, but I don't see where this patch set allows for more than a single extent/range of sectors per TRIM command. If it still does not group many extents into a single TRIM, then it will be far to slow to be useful at all for SATA. But if it does.. my apologies. :) -- 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
