Miller" In-Reply-To: X-Mailer: Mew version 2.1 on Emacs 21.1 / Mule 5.0 (SAKAKI) Mime-Version: 1.0 Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org From: "Thomas Duffy" Date: Fri, 14 Jun 2002 15:00:03 -0700 This part of the patch (the change to kernel/sched.c) can be safely removed without making o1 stop working. If Ingo's changes to remove the "frozen" stuff is installed, the kernel is going to hang when you hit the deadlock condition on sparc64. Unless I'm mistaken, the "frozen" stuff had been removed. You are going to hit this deadlock which I mentioned in another thread on this list when Ingo mentioned that he had removed the "frozen" locking I added because it causes other problems. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
