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.

  mm: memcg: print out cgroup name in the memcg tracepoints
  mm: memcg: introduce new event to trace shrink_memcg
