parentperf evlist: Fix fix for freed id arrays (diff)
perf tools: Fix resource leak of closedir() on the error paths
Both build_mem_topology() and rm_rf_depth_pat() have resource leaks of closedir() on the error paths. Fix this by calling closedir() before function returns. Fixes: e2091cedd51b ("perf tools: Add MEM_TOPOLOGY feature to perf data file") Fixes: cdb6b0235f17 ("perf tools: Add pattern name checking to rm_rf") Signed-off-by: Yunfeng Ye <yeyunfeng@huawei.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Alexey Budankov <alexey.budankov@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Feilong Lin <linfeilong@huawei.com> Cc: Hu Shiyuan <hushiyuan@huawei.com> Cc: Igor Lubashev <ilubashe@akamai.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Martin KaFai Lau <kafai@fb.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Song Liu <songliubraving@fb.com> Cc: Yonghong Song <yhs@fb.com> Link: http://lore.kernel.org/lkml/cd5f7cd2-b80d-6add-20a1-32f4f43e0744@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
