From 3c95c985fa91ecf6a0e29622bbdd13dcfc5ce9f1 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Thu, 17 Feb 2011 18:39:28 +0100 Subject: tty: add TIOCVHANGUP to allow clean tty shutdown of all ttys This is useful for system management software so that it can kick off things like gettys and everything that's started from a tty, before we reuse it from/for something else or shut it down. Without this ioctl it would have to temporarily become the owner of the tty, then call vhangup() and then give it up again.
