[PATCH 0/4] Lockdep: Reduce stack trace memory usage

Hi Peter, An unfortunate side effect of commit 669de8bda87b ("kernel/workqueue: Use dynamic lockdep keys for workqueues") is that all stack traces associated with the lockdep key are leaked when a workqueue is destroyed. Fix this by storing each unique stack trace once. Please consider this patch
