Assisting with kernel Rust development

Hello!

My name is Amy Parker. You may have seen me on the kernel forums before under my previous email address <[email protected]>.

It's been a while since I've attempted to contribute to the kernel, so I figured I'd post here. My previous attempt had been under Matthew Wilcox's direction to modify the DAX driver for NVDIMMs to use XA_ZERO_ENTRY to represent a zero page instead of DAX_ZERO_PAGE (allowing us to save a constant) - but this failed since the ascending values of other flags conflicted with the value presented by XA_ZERO_ENTRY.

I saw the recent patch sequence adding Rust support to the kernel. As a Rust developer, I figured I could get back into kernel development because of this, and was wondering how I could help. Are there any active objectives that need work?
