Yes, it is called "xstat" and is an extensible version of stat which even includes a 'query' bitmap to list which things you want. Unfortunately it never made it to mainline. We should submit a patch to systemd to get it to use xstat instead of name_to_handle_at. That would ensure that the kernel implemented it double-quick :-) NeilBrown
