    coding-style: Clarify the expectations around bool
    
    There has been some confusion since checkpatch started warning about bool
    use in structures, and people have been avoiding using it.
    
    Many people feel there is still a legitimate place for bool in structures,
    so provide some guidance on bool usage derived from the entire thread that
    spawned the checkpatch warning.
