Chris Wilson ae65a21fb8 lib/stackdepot: export save/fetch stack for drivers ... Some drivers would like to record stacktraces in order to aide leak tracing. As stackdepot already provides a facility for only storing the unique traces, thereby reducing the memory required, export that functionality for use by drivers. The code was originally created for KASAN and moved under lib in commit cd11016e5f ("mm, kasan: stackdepot implementation. Enable stackdepot for SLAB") so that it could be shared with mm/. In turn, we want to share it now with drivers.
