| Subject | [PATCH perf/core 19/22] perf: fix hists_evsel to release hists | From | Masami Hiramatsu <> | Date | Wed, 09 Dec 2015 11:11:29 +0900 |
| |
Since hists__init doesn't set the destructor of hists_evsel (which is an extended evsel structure), when hists_evsel is released, the extended part of the hists_evsel is not deleted (note that the hists_evsel object itself is freed).
This fixes it to add a destructor for hists__evsel and to set it up.
