Hi @sanua356 and thanks for the PR.
Sorry for the CI troubles, I've just updated the rust-version in master so you don't need to do it here, but just need to rebase this PR.
Can you please point out where those constants are defined in the mainline Linux kernel? I was not able to find them in the sourcecode.

@lucab Good afternoon! The kernel supporting E2K is distributed as a fork and, unfortunately, is not yet in the mainline. You can view the fork's source code here: https://dev.mcst.ru/download
