From: Oleg Nesterov on 24 Mar 2010 10:30 (fixup for signals-clear-signal-tty-when-the-last-thread-exits.patch) I didn't get this warning, but the old gcc complains kernel/exit.c: In function 'release_task': kernel/exit.c:85: warning: 'tty' may be used uninitialized in this function This clearly wrong, to the point it blames release_task() instead of __exit_signal(). But let's make compiler happy anyway, hopefully this is what it wants.
