Sparse reported warnings about non-static symbols. For the variables a simple static attribute is fine - for the functions referenced by livepatch via klp_func the symbol-names must be unmodified in the symbol table and the patchable code has to be emitted. The resolution is to attach __used attribute to the shared statically declared functions.
