It's very nice of you willing to help check my code! I'm now very excited － problem solved! I spent half a day beautifying my code yesterday (so that it won't annoy you that much), and find there is a problem: Every time there is a read/write system call, I saved the lower file ops and address space ops. In their replacement(upper operations), I invoked lower ones. There's a possibility that it might saved the upper operations as lower ones if I open them twice in a short time. At this point, upper operation invoke itself! So I check the operations before truly save and replace them and, it works! Thanks to you and all the amazing people in this amazing list that helped me, now I get both wrapfs and my own non-filesystem module functional for my future work on transparent encryption, and most importantly, I've learned and enjoyed a lot!
