Date: Sun, 05 Oct 2008 17:22:10 +0100 From: Alan Cox <alan@...hat.com> To: linux-kernel@...r.kernel.org Subject: [PATCH 61/76] pty: Fix allocation failure double free The updating and moving around of the pty code added a bug where both the helper and caller free the main tty struct (the pty driver must free the o_tty pair itself however).
