yeah, please consider using tools/.gitignore. Please have a look at
this thread about ignoring files from "external" tools:
https://lore.kernel.org/lkml/CAHk-=wiJHMje8cpiTajqrLrM23wZK0SWetuK1Bd67c0OGM_BzQ@mail.gmail.com/
If using tools/.gitignore is not possible, I think the best way for
ignoring files that are not natively related to kernel build tools is to
update the local ~/.config/git/ignore, as suggested in
https://lore.kernel.org/lkml/CAK7LNAQas0cK7pgi72tYC3yU=ZkQxnr41YYW1mXd-sWiHtG+UA@mail.gmail.com/
compare to:
https://docs.github.com/en/get-started/git-basics/ignoring-files#configuring-ignored-files-for-all-repositories-on-your-computer
Kind regards,
Nicolas
