Subject: [PATCH tip/core/rcu 27/28] rcutorture: Flag errors and warnings with color coding
From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>
The output of the rcutorture scripts often requires interpretation, so
this commit simplifies this interpretation by tagging messages as
BUGs (colored red) or WARNINGs (colored yellow).
