From 239b7b699e20533f6884134e5007c7708d67317a Mon Sep 17 00:00:00 2001
From: Bruce Evans <bde@FreeBSD.org>
Date: Sat, 6 Dec 1997 13:25:01 +0000
Subject: Use ENOIOCTL instead of -1 (= ERESTART) for tty ioctls that are not
 handled at a particular level.  This fixes mainly restarting of interrupted
 TIOCDRAINs and TIOCSETA{W,F}s.
