From e56d090310d7625ecb43a1eeebd479f04affb48b Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 8 Jan 2006 01:01:37 -0800 Subject: [PATCH] RCU signal handling RCU tasklist_lock and RCU signal handling: send signals RCU-read-locked instead of tasklist_lock read-locked. This is a scalability improvement on SMP and a preemption-latency improvement under PREEMPT_RCU. Signed-off-by: Paul E.
