  "message": "perf: Keep track of the max depth of a callchain\n\nIn order to implement callchains collapsing, we need to keep\ntrack of the maximum depth in a histogram tree of callchains.\nThis way we\u0027ll avoid allocating an arbitrary temporary buffer\nsize on callchain merge time.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\n",
