I am not keen regarding char/block device management, but I think you should separate those streams.

How? Well, same thing like you open a same file twice, right? You're given two different file descriptor. After all, the "open", "read" and "write" handler of device IMHO always assume that we wanna achieve such different stream, right?

Sounds silly but how do I get access to the file descriptor? Also If I make the user create a session for an operation similar to this paper http://www.usenix.org/event/usenix03/tech/full_papers/keromytis/keromytis_ht..., should I remove the read, write operations and do all operations using ioctl commands i.e. reading the user buffer etc?
