The deferred stack trace code wasn't using perf_sample__init/exit. Add the deferred stack trace clean up to perf_sample__exit which requires proper NULL initialization in perf_sample__init. Make the perf_sample__exit robust to being called more than once by using zfree. Make the error paths in evsel__parse_sample exit the sample. Add a merged_callchain boolean to capture that callchain is allocated, deferred_callchain doen't suffice for this. Pack the struct variables to avoid padding bytes for this. Similiarly powerpc_vpadtl_sample wasn't using perf_sample__init/exit, use it for consistency and potential issues with uninitialized variables. Similarly guest_session__inject_events in builtin-inject wasn't using perf_sample_init/exit. The lifetime management for fetched events is somewhat complex there, but when an event is fetched the sample should be initialized and needs exiting on error. The sample may be left in place so that future injects have access to it. Signed-off-by: Ian Rogers <irogers@google.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org>
