Hi Masahiro,

The options are rather limited if we want Rust modules that are
compatible with modversions. We either come up with a way to version
Rust symbols or we bypass version checks for them, which is basically
what Matt's earlier patch set did:

https://lore.kernel.org/rust-for-linux/20231118025748.2778044-1-mmaurer@google.com/

If there are better solutions, I would be happy to hear them.

I picked this location because that's where objtool lives, and wasn't
aware that this was frowned upon. I'm fine with moving the tool
elsewhere too.
