    Subject[PATCH v9 03/27] kallsyms: add static relationship between `KSYM_NAME_LEN{,_BUFFER}`
    Date
    This adds a static assert to ensure `KSYM_NAME_LEN_BUFFER`
    gets updated when `KSYM_NAME_LEN` changes.

    The relationship used is one that keeps the new size (512+1)
    close to the original buffer size (500).
