From: Wang Nan <[email protected]> Introduce a priv field to 'struct format_field' for futher expansion.
(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 <[email protected]> Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: David Ahern <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Sebastian Andrzej Siewior <[email protected]> Cc: Tom Zanussi <[email protected]> Signed-off-by: Jiri Olsa <[email protected]> --- 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 afe20ed9fac8..5ed1ad1461c7 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -6237,6 +6237,8 @@ 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 7a3873ff9a4f..928d801444ab 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 { -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
