Date: Sat, 15 Jun 2013 09:01:00 -0400 From: Peter Hurley <peter@...leysoftware.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.cz> Cc: linux-kernel@...r.kernel.org, linux-serial@...r.kernel.org, Peter Hurley <peter@...leysoftware.com> Subject: [PATCH] tty: Reset itty for other pty Commit 19ffd68f816878aed456d5e87697f43bd9e3bd2b ('pty: Remove redundant itty reset') introduced a regression whereby the other pty's linkage is not cleared on teardown. This triggers a false positive diagnostic in testing. Properly reset the itty linkage.
