We support copy on write (or redirect on write to be correct) now as part of the reflink feature. These out of place writes are a requirement to implement data checksums, as otherwise your data and checksum can not be updated atomically. Everything else is beyond that at this point is vapourware. We'd have to decided first if we really want the feature, and then where to place the checksum (extent structure, rmap, ?). -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
