函数逻辑报告

函数名称：If we have a symbol_name argument, look it up and add the offset field* to it. This way, we can specify a relative address to a symbol.* This returns encoded errors if it fails to look up symbol or invalid* combination of parameters.

函数原型：static kprobe_opcode_t *_kprobe_addr(kprobe_opcode_t *addr, const char *symbol_name, unsigned int offset)

返回类型：kprobe_opcode_t

参数：
