lockdep finds out dependency in locking order at runtime. More on this in kernel documentation linux/Documentation/lockdep-design.txt Rajat On Tue, Feb 1, 2011 at 1:57 AM, Sri Ram Vemulpali <sri.ram.gmu06@gmail.com> wrote:
Hi all,
I am reading spinlock code and looking at struct raw_spinlock. I found struct lockdep_map as member. which is defined as
struct lockdep_map { struct lock_class_key *key; struct lock_class *class_cache[NR_LOCKDEP_CACHING_CLASSES]; const char *name; #ifdef CONFIG_LOCK_STAT int cpu; unsigned long ip; #endif };
Can anyone help me explain, how this struct helps the spinlock. Why do we need lockdepth. Thanks for help in advance. -- Regards, Sri.
