Pushing for additional test coverage exposed minor fixes, a missing
timechart option, and a number of reference counting issues. Fix the
issues then add the new tests. The new tests cover c2c, additional
build-id tests, perf top, timechart, kallsyms, perf script with
 --dlfilter, evlist and kvm.

Ian Rogers (17):
  perf kvm: Fix debug assertion
  perf timechart: Add record support for output perf.data path
  perf symbol-elf: Add missing puts on error path
  perf symbol: Add missed dso__put
  perf probe-event: Ensure probe event nsinfo is always cleared
  perf hist: In init, ensure mem_info is put on error paths
  perf mem-events: Don't leak online CPU map
  perf jitdump: Fix missed dso__put
  perf c2c: Clean up some defensive gets and make asan clean
  perf tests c2c: Add a basic c2c
  perf tests buildid: Add purge and remove testing
  perf tests top: Add basic perf top coverage test
  perf tests timechart: Add a perf timechart test
  perf tests kallsyms: Add basic kallsyms test
  perf tests script dlfilter: Add a dlfilter test
  perf tests evlist: Add basic evlist test
  perf test kvm: Add some basic perf kvm test coverage

Applied to perf-tools-next, thanks!
