But, _require_attr assumes that being able to use "user" namespace xattrs means that all namespaces ("trusted", "system", etc) are supported. This breaks on NFS, that only supports the "user" namespace, and a few cases in the "system" namespace. Change _require_attrs to optionally take namespace arguments that specify the namespaces to check for. The default behavior (no arguments) is still to check for the "user" namespace only.
