Default file_operations methods?

Hi everyone, I'm testing out a small kernel module and wondered what the default file_operations methods are. I know about no_llseek for llseek, but what about the rest? Is there anything like no_llseek for e.g. read, write and so on? The reason I'm asking this is that my module should only allow opening, closing, and calling a couple ioctls. Reading, writing and such wouldn't make sense here.
