From 33b2b93bd831fc0e994654cef3d046c713e3b55e Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 3 Apr 2020 14:12:07 -0700 Subject: rcu: Remove self-stack-trace when all quiescent states seen When all quiescent states have been seen, it is normally the grace-period kthread that is in trouble. Although the existing stack trace from the current CPU might possibly provide useful information, experience indicates that there is too much noise for this to be worthwhile. This commit therefore removes this stack trace from the output. Signed-off-by: Paul E.
