perf script: Simplify auxiliary event printing functions
This simplifies the print functions for the following perf script options: --show-task-events --show-namespace-events --show-cgroup-events --show-mmap-events --show-switch-events --show-lost-events --show-bpf-events Example: # perf record --switch-events -a -e cycles -c 10000 sleep 1 Before: # perf script --show-task-events --show-namespace-events --show-cgroup-events --show-mmap-events --show-switch-events --show-lost-events --show-bpf-events > out-before.txt After: # perf script --show-task-events --show-namespace-events --show-cgroup-events --show-mmap-events --show-switch-events --show-lost-events --show-bpf-events > out-after.txt # diff -s out-before.txt out-after.txt Files out-before.txt and out-after.tx are identical Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20200402141548.21283-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
