Maybe a better way would be for the module to install a syscall or similar entry, and the userspace program could provide a buffer to store the data in. Then, kernel space wouldn't have to worry about masses of data, and just use copy_to_user() to transfer the data into the given buffer. When the program wants to finish gathering data, they just call another system call, and maybe have another system call for changing buffers. You might also have a signal that is delivered when the buffer needs changing.
