Date: Wed, 27 Mar 2013 07:43:51 -0400 From: Peter Hurley <peter@...leysoftware.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.cz> Cc: linux-serial@...r.kernel.org, linux-kernel@...r.kernel.org, Min Zhang <mzhang@...sta.com>, Ilya Zykov <linux@...k.ru>, Peter Hurley <peter@...leysoftware.com> Subject: [PATCH v2 01/18] tty: Don't change receive_room for ioctl(TIOCSETD) tty_set_ldisc() is guaranteed exclusive use of the line discipline by tty_ldisc_lock_pair_timeout(); shutting off input by resetting receive_room is unnecessary.
