    SubjectRe: [PATCH 11/11] dynamic_debug: use a single printk() to emit msgs

    I know. What I'm trying to explain is that since patch 11/11 modifies
    dynamic_emit_prefix() such that it writes its output to a buffer there
    is no longer a need to write into that buffer with a single snprintf()
    call. Using multiple snprintf() calls is also fine. Hence it is
    possible to eliminate the two temporary arrays (tid[] and lineno[])
    from dynamic_emit_prefix() without reintroducing these races.
