With oplocks you can implement "lease" (and therefore "coherent") for file data reads and writes, at least. I'm not sure if it also covers attributes and directory operations. You would use NT_TRANSACT_NOTIFY_CHANGE for "queued" when possible, because it's much cheaper and intended for this, although you could use oplocks (expensively) for this too. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
