From 14d47d545c78e44e8ace72116589d77017f78d1e Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 25 Oct 2012 17:59:23 -0700 Subject: [PATCH] rcu: Reduce default RCU CPU stall warning timeout The RCU CPU stall warning timeout has defaulted to 60 seconds for some years, with almost no false positives. This commit therefore reduces the default to 21 seconds, slightly shorter than the new soft-lockup timeout. Signed-off-by: Paul E.
