Phoronix: Microsoft Engineer Ports EXT2 File-System Driver To Rust

Back in late 2023 were Rust abstractions for the Linux kernel's Virtual File-System (VFS) code. Those patches by Microsoft engineer Wedson Almeida Filho have now seen a second iteration posted... In addition to various improvements to the Rust VFS bindings, the new patches bring a work-in-progress EXT2 Rust file-system driver...

This doesn't make much sense unless they use this as a proof of concept and add an NTFS or ReFS driver later.

It makes sense if you compare the LOC of rust vs. the recently removed C LOC. Demonstratio of the abilities...

ext4 and btrfs would be a start...NTFS and especially ReFS would be too much progress for them.

Lets call them the same as any other language when it needs to consume standard C APIs.

Well yes, sure it is a proof of concept. It is easier to test the design of an VFS abstraction with having some real filesystem to play with.

They may need something to test against

The complexity of NTFS is likely much higher that ext2.

That's why full NTFS support - or even ReFS - would that much of a better proof of concept.

to much work for nothing, probably is just to test and mature rust in the kernel
