Subject: [PATCH 11/37] perf trace: Drop thread refcount in trace__event_handler()
Date: Thu, 25 Oct 2018 08:10:05 -0300 [thread overview]
Message-ID: <20181025111031.3440-12-acme@kernel.org> (raw)
In-Reply-To: <20181025111031.3440-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
We must pair:
thread = machine__findnew_thread();
with thread__put(thread). Fix it.
