    I was looking at lockdep-desing.txt and i guess i am confused with the
    changes with respect to fd7bcea3
    
    . It
    says
    
    +   '.'  acquired while irqs enabled
    +   '+'  acquired in irq context
    +   '-'  acquired in process context with irqs disabled
    +   '?'  read-acquired both with irqs enabled and in irq context
    +
    
    But the get_usage_chars() function does this for '-'
     if (class->usage_mask & LOCKF_ENABLED_HARDIRQS)
                            *c1 = '-';
    
    So i guess what would be correct would be
    '.'  acquired while irqs disabled
    '+'  acquired in irq context
    '-'  acquired with irqs enabled
    '?' read acquired in irq context with irqs enabled.
