    Subject[PATCH 25/27] lru_cache: Remove use of seq_printf return value
    Date
    The seq_printf return value, because it's frequently misused,
    will eventually be converted to void.

    See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
    seq_has_overflowed() and make public")
