26 limiting the availability of a set of symbols for use in other parts of the
27 kernel. As of today, modules that make use of symbols exported into namespaces,
34 Symbols can be exported into namespace using different methods. All of them are
42 exporting of kernel symbols to the kernel symbol table, variants of these are
43 available to export symbols into a certain namespace: EXPORT_SYMBOL_NS() and
