From d29f3ef39be4eec0362b985305fc526d9be318cf Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 3 May 2012 22:24:08 +0100 Subject: tty_lock: Localise the lock In each remaining case the tty_lock is associated with a specific tty. This means we can now lock on a per tty basis. We do need tty_lock_pair() for the pty case. Uglier but still a step in the right direction.
