perf bench futex: Fix memory leak of perf_cpu_map__new()
ASan reports memory leaks while running: $ sudo ./perf bench futex all The leaks are caused by perf_cpu_map__new not being freed. This patch adds the missing perf_cpu_map__put since it calls cpu_map_delete implicitly. Fixes: 9c3516d1b850ea93 ("libperf: Add perf_cpu_map__new()/perf_cpu_map__read() functions") Signed-off-by: Sohaib Mohamed <sohaib.amhmd@gmail.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: André Almeida <andrealmeid@collabora.com> Cc: Darren Hart <dvhart@infradead.org> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Sohaib Mohamed <sohaib.amhmd@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lore.kernel.org/lkml/20211112201134.77892-1-sohaib.amhmd@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
