I have no idea what the hang case is, but from a quick look, the code for the tooling part (beside few nitpicks) looks good to me.

[PATCH 0/7 V4] perf: Enable mmap2 and add dcacheline sorting
These patches enable mmap2 support in the kernel and perf to allow support for data cacheline sorting. Note: I haven't been able to reproduce Jiri's perf hang yet, so I don't have a patch for that particular problem yet. V4: reworked setting up cacheline size (Jiri Olsa) V3: added patch to get cacheline size at runtime updated some changelogs fix a test failure (after install libunwind-devel) fix header column length V2: change cacheline to dcacheline (Namhyung Kim) change dcacheline alogorithm a bit re-order mmap2 patches (Namhyung Kim) provide documentation (Andi Kleen) Don Zickus (7): events, perf: Pass protection and flags bits through mmap2 interface Revert "perf: Disable PERF_RECORD_MMAP2 support" perf: Update mmap2 interface with protection and flag bits perf report: Add mem-mode documentation to report command perf: Add cpumode to struct hist_entry perf: Add support to dynamically get cacheline size perf: Add dcacheline sort include/uapi/linux/perf_event.h | 1 + kernel/events/core.c | 37 +-- tools/perf/Documentation/perf-report.txt | 23 +++ tools/perf/builtin-report.c | 2 +- tools/perf/perf.c| 5 ++ tools/perf/tests/dwarf-unwind.c | 2 +- tools/perf/util/cpumap.c | 27 tools/perf/util/cpumap.h | 3 + tools/perf/util/event.c | 59 +++-- tools/perf/util/event.h | 2 + tools/perf/util/evsel.c | 1 + tools/perf/util/hist.c | 9 ++- tools/perf/util/hist.h | 1 + tools/perf/util/machine.c| 4 +- tools/perf/util/map.c| 4 +- tools/perf/util/map.h| 4 +- tools/perf/util/sort.c | 108 +++ tools/perf/util/sort.h | 2 + tools/perf/util/util.c | 1 + tools/perf/util/util.h | 1 + 20 files changed, 265 insertions(+), 31 deletions(-) -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
