From fc0a2c1d59beac70b8738f4ce14431b798837374 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 12 Feb 2016 16:43:02 -0300 Subject: [PATCH] perf tools: Introduce parse_events_terms__purge() Purges 'struct parse_event_term' entries from a list_head. Some users need this because they don't allocate space for the list head, it maybe on the stack or embedded into some other struct. Next patch will convert users that need just purging and then the perf_events__free_terms() routine will free the list head as well, finally being renamed to perf_events_terms__delete().
