On related news, I've just posted FunctionFS driver. :) It's still imperfect

Yes, that should solve the gadgetfs issue for you, right Felipe?

sure it should. Will take a look at it :-)
As I've said it's still imperfect. In particular the throughput won't be
impressive but that's on the TODO list (I first want to put a real driver
on top of FunctionFS before optimising the code) and in particular u_char
seem to be a good piece to steal code from. ;) Still, as said, I haven't
analysed possible optimisations just yet.
All in all, I believe FunctionFS can work for you as you will handle data
transfers in user space anyway. At the same time FunctionFS solves evens
end setup requests communication (I'm still wondering whether it would be
better to use separate file for events and for setup requests).
