Message-Id: <1358980578-8811-1-git-send-email-Karthik.Manamcheri@ni.com> Date: Wed, 23 Jan 2013 16:36:18 -0600 From: Karthik Manamcheri <Karthik.Manamcheri@...com> To: linux-serial@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Karthik Manamcheri <Karthik.Manamcheri@...com> Subject: [PATCH] n_tty: Unthrottle tty when flushing read buffer When the tty input buffer is full and thereby throttled, flushing/resetting the read buffer should unthrottle to allow more data to be received.
