You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: detection.rs
    path of file: ./repos/cuneiform/src
    
    the code of the file until where you have to start completion: use super::CuneiformArgs;

#[cfg(target_os = "linux")]
use super::slabs::FALLBACK_COHERENCE_LINE_SIZE;
#[cfg(target_os = "linux")]
use std::fs;
#[cfg(target_os = "linux")]
use walkdir::WalkDir;

#[cfg(target_os = "linux")]
const LINUX_CPU_PROC_PROBE: &'static str = "/sys/devices/system/cpu/";

    
pub(crate) fn hermetic_detection(_args: CuneiformArgs) -> usize {
    let mut ways = Vec::<usize>::new();
    for entry in WalkDir::new(LINUX_CPU_PROC_PROBE)
        .into_iter()
        .filter_map(|e| e.ok())
        .filter(|e| e.path().ends_with(CACHE_LINE_PROBE))
    {
        let clps =
            fs::read_to_string(entry.path()).expect("Unexpected failure reading cache line probe");
        let clps = clps.trim();
        let clp = clps.parse::<usize>().unwrap();
        ways.push(clp);
    }

    ways.iter()
        .min()
        .map_or(FALLBACK_COHERENCE_LINE_SIZE as usize, |e| *e)
}
