Due to that, it is better to disable the "no-" prefix for them, since otherwise, the later opt-parsing segfaults. Before: $ perf stat --no-metrics -- ls Segmentation fault (core dumped) After: $ perf stat --no-metrics -- ls Error: option `no-metrics' isn't available Usage: perf stat [<options>] [<command>] Signed-off-by: Michael Petlan <mpetlan@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> LPU-Reference: 1485912065.62416880.1544457604340.JavaMail.zimbra@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
