From: Dmitry Rokosov <ddrokosov@xxxxxxxxxxxxxx> The motivation behind this commit is to enhance the traceability and understanding of memcg events. By integrating the function cgroup_name() into the existing memcg tracepoints, this patch series introduces a new tracepoint template for the begin() and end() events. It utilizes a static __array() to store the cgroup name, enabling developers to easily identify the cgroup associated with a specific memcg tracepoint event. Additionally, this patch series introduces new shrink_memcg tracepoints to facilitate non-direct memcg reclaim tracing and debugging.
