No love for memccpy() in the kernel (note, two 'c's, this is not memcpy())?

This has apparently been in POSIX forever, and is also supposedly going to be part of C2X.

And the nice documentation here says "To avoid the risk of buffer overflow" and produces an example that uses the returned pointer p without checking if p was NULL, which is may reasonably be. :)
