I'm not quite able to parse this ramble here, but if you're upset that
the kernel interface isn't as nice as it should be, I share your
dismay. I've only inherited it after a several decade development
history of warts. I'm doing my best to clean up the kernel interface,
but compatibility is important, and there will always be old kernels.
So the interface is what it is, and that means addressing complex
error cases and ugly ioctls. Sorry.
