Don't know if injecting rockusb protocol in f_mass_storage.c will be acceptable in terms of coexistence and maintainability of resulting f_mass_storage.c Do you plan to upstream your tree? I saw patches in your tree and resulting f_rockusb.c is more clear yes. But we pay the price in f_mass_storage.c.
