    [PATCH] Provide better printk() support for SMP machines · fe21773d
    David Howells authored Sep 06, 2005
    
    
    The attached patch prevents oopses interleaving with characters from
    other printks on other CPUs by only breaking the lock if the oops is
    happening on the machine holding the lock.
    
    It might be better if the oops generator got the lock and then called an
    inner vprintk routine that assumed the caller holds the lock, thus
    making oops reports "atomic".
