From e1a2509023785bd3199ac068ab80155aeba01265 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Mon, 10 Apr 2006 22:54:05 -0700 Subject: [PATCH] [PATCH] make tty_insert_flip_string_flags() a non gpl export We changed the wrong symbol. It's tty_insert_flip_string_flags() which is called from the previously-non-GPL'ed now-inlined tty_insert_flip_char(). Fix that up, and uninline tty_schedule_flip() while we're there.
