From 3b80df7ca7e2fec76be2eda304cc7e0eb90f911d Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 15 Jun 2013 09:14:13 -0400 Subject: 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.
