35 * Export symbols for module (mmfslinux)
36 *
37 * Define new global variables with GPFS_EXPORT_SYMBOL(varname).
38 * Define new functions with GPFS_EXPORT_FUNC(varname).
39 *
40 * The latter will automatically spit out a generic function
41 * prototype. The prototype format doesn't matter here, but
42 * it is important to let the compiler know that something
43 * is really a function (or else incorrect code is spewed out
44 * on IA64 for the relocation entry which trips up insmod;
45 * the i386 platform doesn't have this feature).
46 *
47 * NOTE: C++ function names / methods are generally mangled and
48 * you need to use the managled symbol name. The mangled name can
49 * be found by scanning the appropriate object file w/
50 * "objdump --syms <file> | grep <original symbol name>", or just
51 * try to load the module and shove the undefined reference names
52 * in here.
53 * These mangled names seem to be architecture independant so far.
