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 ?
