perf list: Honour 'event_glob' whem printing selectable PMUs
Some PMUs, like the 'intel_bts' one can be used as an event name, i.e.: $ perf record -e intel_bts:// usleep 1 Is a valid event name. But the code printing such PMUs was not honouring the 'event_glob' parameter, so the following line was always appearing: $ intel_bts// [Kernel PMU event] Fix it: $ [acme@felicio linux]$ perf list data List of pre-defined events (to be used in -e): uncore_imc/data_reads/ [Kernel PMU event] uncore_imc/data_writes/ [Kernel PMU event] $ Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-ajb71858n7q7ao77b8pyy74w@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
