Subject: [PATCH] Work around dead_code warning in flock implementation

    warning: field `0` is never read
      --> src/flock.rs:22:12
       |
    22 |     Locked(MutexGuard<'static, ()>),
       |     ------ ^^^^^^^^^^^^^^^^^^^^^^^
       |     |
       |     field in this variant
       |
       = note: `#[warn(dead_code)]` on by default
    help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field
