Date: Fri, 27 Nov 2015 21:25:51 -0500 From: Peter Hurley <peter@...leysoftware.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Jiri Slaby <jslaby@...e.cz>, linux-kernel@...r.kernel.org, Peter Hurley <peter@...leysoftware.com> Subject: [PATCH 06/12] tty: Remove __lockfunc annotation from tty lock functions The tty lock/unlock code does not belong in the special lockfunc section which is treated specially by stack backtraces.
