Only symbols for which EXPORT_SYMBOL or EXPORT_SYMBOL_GPL with that symbol as argument is stated somewhere are visible to modules. Almost all (but there are few exceptions) these "directives" appear in kernel/ksyms.c. AFAICS looking there, get_kernel_syms is not exported, so you can't use it from modules unless you add it to kernel/ksyms.c and recompile kernel. (The reason for this is, that kernel is size critical and so only symbols that are actualy needed by some modules are exported.) ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
