  "message": "perf tools: Set the maximum allowed stack from /proc/sys/kernel/perf_event_max_stack\n\nThere is an upper limit to what tooling considers a valid callchain,\nand it was tied to the hardcoded value in the kernel,\nPERF_MAX_STACK_DEPTH (127), now that this can be tuned via a sysctl,\nmake it read it and use that as the upper limit, falling back to\nPERF_MAX_STACK_DEPTH for kernels where this sysctl isn\u0027t present.\n\nCc: Adrian Hunter \u003cadrian.hunter@intel.com\u003e\nCc: Brendan Gregg \u003cbrendan.d.gregg@gmail.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Jiri Olsa \u003cjolsa@kernel.org\u003e\nCc: Milian Wolff \u003cmilian.wolff@kdab.com\u003e\nCc: Namhyung Kim \u003cnamhyung@kernel.org\u003e\nCc: Wang Nan \u003cwangnan0@huawei.com\u003e\nLink: http://lkml.kernel.org/n/tip-yjqsd30nnkogvj5oyx9ghir9@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n",
