lockdep_free_key_range_imm

Name:Free all lockdep keys in the range [start, start+size). Does not sleep.* Ignores debug_locks. Must only be used by the lockdep selftests.

Proto:static void lockdep_free_key_range_imm(void *start, unsigned long size)

Type:void

Parameter:

Type	Parameter	Name
void *	start
unsigned long	size

5045

Initialize the lock_classes[] array elements, the free_lock_classes list* and also the delayed_free structure.

r sched/core.c and kernel_lock.c: ( & lockdep_lock: protects the lockdep graph, the hashes and the* class/list/hash allocators.* This is one of the rare exceptions where it's justified* to use a raw spinlock - we really dont want the spinlock* code to recurse back into the lockdep code...)

5049

Remove all lock classes from the class hash table and from the* all_lock_classes list whose key or name is in the address range [start,* start + size). Move these lock classes to the zapped_classes list. Must* be called with the graph lock held.

5050

The caller must hold the graph lock. May be called from RCU context.
