That's certainly the easy way out. You'll need a good way to actually transport the ranges as we can't simply sote them in bi_sector/bi_size and adapt the whole block layer to deal with the two types of different discards. Not saying it's impossible, but when I tried it before it wasn't pretty. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
