If its so unacceptable why has nobody noticed until now - its a bug
clearly, it needs fixing clearly, but unless you can produce some kind of
exploit from it (eg a DoS attack or kernel memory leak exploiter) it
doesn't appear to be that serious.

If you put ugly code into the kernel you pay for maintaining it for years
to come. If you get it right then you don't

And it'll get NAKked and binned. DaveM is (as happens sometimes ;)) right
to insist on the code being clean and efficient.
