Subject: [PATCH] binder: Add invalid handle info in user error log
Date: Mon,  2 Aug 2021 17:41:38 +0000	[thread overview]
Message-ID: <20210802174139.1908760-1-ramjiyani@google.com> (raw)

In case of a fail transaction to the target node; user error log currently
only prints the thread and process id. Add handle info for the reference
to the target node in user error log to aid debugging.
