using kvzalloc() simplifies the code by avoiding the
use of different memory allocation functions for different
situations, making the code more uniform and readable.

No need to create an account if submitting by email, that will happen
automatically on the successful receipt of a patch, except of course
with password access blocked until a "forgotten password" thing is
done.
