Subject: [PATCH 0/5] debugobjects: Do some minor optimizations, fixes and cleaups

The summary changes of the first two patches is as follows:
 if (likely(READ_ONCE(obj_pool_free) >= debug_objects_pool_min_level))
	return;

- while (READ_ONCE(obj_nr_tofree) && (READ_ONCE(obj_pool_free) < obj_pool_min_free)) {
+ if (READ_ONCE(obj_nr_tofree)) {
	raw_spin_lock_irqsave(&pool_lock, flags);
-	while (obj_nr_tofree && (obj_pool_free < obj_pool_min_free)) {
+	while (obj_nr_tofree && (obj_pool_free < debug_objects_pool_min_level)) {
		... ...
	}
	raw_spin_unlock_irqrestore(&pool_lock, flags);


Zhen Lei (5):
  debugobjects: Fix the misuse of global variables in fill_pool()
  debugobjects: Remove redundant checks in fill_pool()
  debugobjects: Don't start fill if there are remaining nodes locally
  debugobjects: Use hlist_splice_init() to reduce lock conflicts
  debugobjects: Delete a piece of redundant code
