  "message": "perf tools: Add attr-\u003emmap2 support\n\nThis patch adds support for the new PERF_RECORD_MMAP2 record type\nexposed by the kernel. This is an extended PERF_RECORD_MMAP record.\n\nIt adds for each file-backed mapping the device major, minor number and\nthe inode number and generation.\n\nThis triplet uniquely identifies the source of a file-backed mapping. It\ncan be used to detect identical virtual mappings between processes, for\ninstance.\n\nThe patch will prefer MMAP2 over MMAP.\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Jiri Olsa \u003cjolsa@redhat.com\u003e\nCc: Namhyung Kim \u003cnamhyung.kim@lge.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1377079825-19057-3-git-send-email-eranian@google.com\n[ Cope with 314add6 \"Change machine__findnew_thread() to set thread pid\",\n  fix \u0027perf test\u0027 regression test entry affected,\n  use perf_missing_features.mmap2 to fallback to not using .mmap2 in older kernels,\n  so that new tools can work with kernels where this feature is not present ]\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n",
