3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Tomas Bortoli tomasbortoli@gmail.com
commit 430ac66eb4c5b5c4eb846b78ebf65747510b30f1 upstream.
The patch adds the flush in p9_mux_poll_stop() as it the function used by p9_conn_destroy(), in turn called by p9_fd_close() to stop the async polling associated with the data regarding the connection.
