If you want to do the read-modify write cycle properly you'll have to do it at the time the invalid extent is read, not written. Take a look at my patch to add a flag to do that in page 5, although it would be a lot more involved to do it for large pnfs block sizes. Given that the code never really fully worked beforehand I'm not tempted to come up with that myself, though. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
