perf tools mem: Fix -t store option for record command
Michael reported 'perf mem -t store record' being broken. The reason is latest rework of this area: commit acbe613e0c03 ("perf tools: Add monitored events array") We don't mark perf_mem_events store record when -t store option is specified. Committer notes: Before: # perf mem -t store record usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ] # perf evlist cycles:ppp # After: # perf mem -t store record usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ] # perf evlist cpu/mem-stores/P # Reported-by: Michael Petlan <mpetlan@redhat.com> Signed-off-by: Jiri Olsa <jolsa@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Fixes: acbe613e0c03 ("perf tools: Add monitored events array") Link: http://lkml.kernel.org/r/1470905457-18311-1-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
