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