McKenney" , "Eric W. Biederman" , Roland McGrath Subject: [PATCH 0/4] prepare for ->siglock safe threads traversal 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 Content-Length: 531 Lines: 14 The main problem is that copy_process's error path and release_task() share __exit_signal() which locks ->sighand and destroys it, but we need to do __unhash_process() under ->sighand. This patch series tries to solves this. It also tries to simplify and cleanup the code a bit.
