    printk: Hide console waiter logic into helpers · ef433725
    Petr Mladek authored
    [ Upstream commit c162d5b4 ]
    The commit ("printk: Add console owner and waiter logic to load balance
    console writes") made vprintk_emit() and console_unlock() even more
    This patch extracts the new code into 3 helper functions. They should
    help to keep it rather self-contained. It will be easier to use and
    This patch just shuffles the existing code. It does not change
    the functionality.
