Subject: [PATCH v8 2/3] binder: add trace at free transaction.
Date: Mon, 7 Sep 2020 20:00:54 +0800 [thread overview]
Message-ID: <1599480055-25781-3-git-send-email-Frankie.Chang@mediatek.com> (raw)
In-Reply-To: <1599480055-25781-1-git-send-email-Frankie.Chang@mediatek.com>
From: "Frankie.Chang" <Frankie.Chang@mediatek.com>
Since the original trace_binder_transaction_received cannot
precisely present the real finished time of transaction, adding a
trace_binder_txn_latency_free at the point of free transaction
may be more close to it.
