Can you reformat this to match rusfmt formatting? Unfortunately rustfmt doesn't auto-format code in macro blocks.

Implements the WaitableChild struct for
freebsdsystems. In addition, the Wait approach will be used by default for freebsd systems.The PR explicitly implements the WaitableChild only for
freebsd, that is because of the lack of testing in other BSD systems. I would expect other systems supporting thekqueueevent notification interface to work as well (NetBSD, OpenBSD, DragonFly BSD, and macOS). Would it make sense to extend the implementation to cover these OSes too?Usage of smol-rs/async-io#207
Tests: all tests run with the WaitableChild instance.
