As we propagate window changes to both it doesn't currently matter but will when we tidy up the pty termios logic a bit more Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds --- diff --git a/drivers/char/tty_io.c b/drivers/char/tty_io.c index ac53d7f9b5d..9a76db3cda1 100644 --- a/drivers/char/tty_io.c +++ b/drivers/char/tty_io.c @@ -2133,7 +2133,7 @@ int tty_do_resize(struct tty_struct *tty, struct tty_struct *real_tty, /* For a PTY we need to lock the tty side */ mutex_lock(&real_tty->termios_mutex); - if (!memcmp(ws, &tty->winsize, sizeof(*ws))) + if (!memcmp(ws, &real_tty->winsize, sizeof(*ws))) goto done; /* Get the PID values and reference them so we can avoid holding the tty ctrl lock while sending signals */
