Yes, and this is the statement I was looking for. IF(!) this really is the case, then we don't have anything to worry about because new kernel with old container will look at ->datasize, see 0 and return DEFAULT_UCODE_TOTALSIZE and we're fine.
I've updated the patch with your additional explanation.
Thanks.
