My first patch: Implement InPlaceInit for Arc

[alexmantel93]

Greetings!

This is my very first patch for Linux. I have lifted my arms up, placed my hands on my head, and tensed my non-existent abs. Punch as hard as you can! 🙂 I am happy to receive any feedback or critique, especially regarding whether these are the correct mailing lists for the patch.

Over the past few weeks, I have read a lot of the kernel documentation. However, if I missed any crucial parts, please just point me to the chapters I need to read, particularly concerning the mailing list part.

This patch about Rust-for-Linux, specifically for the in-place initialization:

Kind regards, Alex
