[PATCH tip/core/rcu 13/55] rcutorture: Flag tests requiring more CPUs than are available

From: Paul E. McKenney
Date: Mon Feb 17 2014 - 17:28:00 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>

This commit adds a "(!)" flag after the number of CPUs required by a
given test if that test requires more than the available number of CPUs.
Note that these flags appear only when the number of CPUs is specified
using the --cpus argument. In the absence of a --cpus argument, no
tests are flagged.
