(In https://lkml.org/lkml/2015/1/21/383 , Jiri Olsa gives a suggestion about changing lib traceevent to solve a bug of perf-convert-to-ctf, which is related to duplicated field names. I think his suggestion should be something like this patch. ) Signed-off-by: Wang Nan --- tools/lib/traceevent/event-parse.c | 2 ++ tools/lib/traceevent/event-parse.h | 2 ++ 2 files changed, 4 insertions(+) diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index cf3a44b..5f76003 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -5909,6 +5909,8 @@ static void free_format_fields(struct format_field *field) free(field->type); free(field->name); free(field); + if (field->destroy_priv) + field->destroy_priv(field); field = next; } } diff --git a/tools/lib/traceevent/event-parse.h b/tools/lib/traceevent/event-parse.h index 7a3873f..928d801 100644 --- a/tools/lib/traceevent/event-parse.h +++ b/tools/lib/traceevent/event-parse.h @@ -190,6 +190,8 @@ struct format_field { unsigned int arraylen; unsigned int elementsize; unsigned long flags; + void *priv; + void (*destroy_priv)(struct format_field *); }; struct format { -- 1.8.4
