@sylvestre hi, sorry, missed previous message, will try to address this this or next week, thanks 👋

Hi, sorry, life happened, and then rust update forced me to fight with llvm installation 😢
Can't test that spellcheck change, based it on other uses inside the file, hope it's ok.

P.S. want me to rebase and/or squash the branch?

GNU testsuite comparison:

Skip an intermittent issue tests/tail/inotify-dir-recreate (fails in this run but passes in the 'main' branch)
Congrats! The gnu test tests/timeout/timeout is no longer failing!

The diff looks good to me, and could be merged.

Please rebase on top of current main; there are many CI failures, and since this branch is roundabout 150 commits behind it, I'd like to see a (more) successful run first.

[gim913]

Hello, are the two failures visible above something known?
I've tried looking at produced android artifacts (screenshots), but they're not super helpful.

Yes, the Android tests currently also fail for other PRs and hence are unrelated to this PR. Some of the other failing tests, however, are related to your PR :|

[BenWiederhake]

LGTM, remaining CI failures are a known issue (fixed by #6762).
