Subject: [PATCH] binder: fix incorrect cmd to binder_stat_br
Date: Tue, 8 Aug 2017 15:48:36 -0700 [thread overview]
Message-ID: <20170808224836.38951-1-tkjos@google.com> (raw)
commit 26549d177410 ("binder: guarantee txn complete / errors delivered
in-order") passed the locally declared and undefined cmd
to binder_stat_br() which results in a bogus cmd field in a trace
event and BR stats are incremented incorrectly.
Change to use e->cmd which has been initialized.
