Heres the action's log about failure, but it doesn't happen on my Debian testing.

It only happend on freebsd target I think.

coreutils::tests test_sort::test_output_is_input's failure may not caused by this PR after my check.

could you please fix the windows clippy warnings too as you are working on it ?

I'll fix it later

Here's a lots of denied warnings about clippy::cognitive_complexity

There are two solutions

• Change the configuration of cognitive-complexity-threshold in .clippy.toml from 10 to 71, avoid changing the unit testing function name
• Change from 10 to 24 and rename only one unit testing function name

Skip an intermittent issue tests/tail/inotify-dir-recreate (fails in this run but passes in the 'main' branch)

There are two solutions

* Change the configuration of `cognitive-complexity-threshold` in `.clippy.toml` from `10` to `71`, avoid changing the unit testing function name

* Change from `10` to `24` and rename only one unit testing function name

I think add #[allow(clippy::cognitive_complexity)] would be better because of the clap made a good example.

So I'll add #[allow(clippy::cognitive_complexity)] to resolve the issues.
