From 6c70e9cd5f3c6d93f3e1da6d101073e898f39170 Mon Sep 17 00:00:00 2001 From: Neeraj Upadhyay Date: Fri, 8 Mar 2019 11:57:48 -0800 Subject: rcu: Fix nohz status in stall warning The Documentation/RCU/stallwarn.txt file says that stall warnings print "D" if dyntick-idle processing is enabled, but the code in print_cpu_stall_fast_no_hz() prints "." instead. This commit therefore reverses the sense of the test to make the code match the documentation. Signed-off-by: Neeraj Upadhyay Signed-off-by: Paul E.
