OK, there's merit in this approach: it certainly moves the argument
about how to encode the signature out of my backyard :)
Should we just bite the bullet and create a new syscall:
SYSCALL_DEFINE5(init_module2, void __user *, umod,
unsigned long, len, const char __user *, uargs,
unsigned int, siglen, const char __user *, sig)
But I'm easily swayed if you prefer the current approach.
Thanks,
Rusty.
