I agree, but it seems inconsistent with the xattr / directory thing. Because that *is* mapping metadata. They may have no data blocks; it's been suggested they return extents covering metadata locations only. It seems the same use-cases where you might want metadata location from xattrs and directories apply equally to metadata locations for a file. I.e. knowing which parts of a disk will be accessed. -- 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
