From 5fcce7432a731e67f1cd3ef1e71dca9ea84dedb1 Mon Sep 17 00:00:00 2001 From: Aneesh Kumar Date: Wed, 11 Oct 2006 01:22:07 -0700 Subject: [PATCH] fix lockdep-design.txt 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.
