Actually we don't tag any I/O that way right now.

We'll need a properly defined REQ_META to use it, which currently is not the case. -- 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
