Tux was a nice experiment, until somebody showed that you can get the
same performance from userspace by using sendfile(). The performance
argument no longer holds.
Agreed, but I believe there are still some gray areas. For example,
using multiple streams for transfering a file. Yes, this can be done in
the user mode, probably as effectively, but doing it in the kernel is
still an interesting thing to do.
If you mean "interesting" as in "interesting ways to crash your kernel
by minor programming errors", I agree.
My point is don't discourage people just by saying 'don't do this', when
there are possible useful scenarios. What's wrong, if someone crashes
the kernel, while learning? If nothing else, one would atleast learn a
few intricacies of the kernel.
