Add map_groups__merge_in test to test the map_groups__merge_in function usage - merging kcore maps into existing eBPF maps. Committer testing: # perf test merge 59: map_groups__merge_in : Ok # perf test -v merge 59: map_groups__merge_in : --- start --- test child forked, pid 8349 test child finished with 0 ---- end ---- map_groups__merge_in: Ok # Signed-off-by: Jiri Olsa <jolsa@kernel.org> Acked-by: Song Liu <songliubraving@fb.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stanislav Fomichev <sdf@google.com> Link: http://lkml.kernel.org/r/20190508132010.14512-10-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
