strtomem_pad seems redundant with memcpy_and_pad, and also it requires the preprocessor: https://github.com/torvalds/linux/blob/1a3746ccbb0a97bed3c06...

I was curious: Why have it, instead of just using memcpy_and_pad?

AI's answer (paraphrased) was * Avoid possible bugs from manually write sizeof(dest) * Enforces the __nonstring Attribute * signals: "I am converting an actual C-string into a fixed-width legacy memory field." vs copy binary data & pad it.

Interesting to learn about the __nonstring attribute:
