Subject: [PATCH] binder: filter out nodes when showing binder procs
Date: Mon,  3 Dec 2018 12:24:56 -0800	[thread overview]
Message-ID: <20181203202457.228972-3-tkjos@google.com> (raw)
In-Reply-To: <20181203202457.228972-1-tkjos@google.com>

When dumping out binder transactions via a debug node,
the output is too verbose if a process has many nodes.
Change the output for transaction dumps to only display
nodes with pending async transactions.
