Subject[PATCH] lockdep-design.txt
Hi Ingo,

I was looking at lockdep-desing.txt and i guess i am confused with the
changes with respect to fd7bcea35e7efb108c34ee2b3840942a3749cadb. 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.

Is this correct ?

Unused mutexes cannot be part of the cause of an error.
