From: Ian Rogers Date: Tue, 24 Jun 2025 19:03:21 +0000 (-0700) Subject: perf dso: Add missed dso__put to dso__load_kcore X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=63a088e999de3f431f87d9a367933da894ddb613;p=users%2Fjedix%2Flinux-maple.git perf dso: Add missed dso__put to dso__load_kcore The kcore loading creates a set of list nodes that have reference counted references to maps of the kcore. The list node freeing in the success path wasn't releasing the maps, add the missing puts. It is unclear why this leak was being missed by leak sanitizer.
