[PATCH tip/core/rcu 05/13] rcutorture: Correct no-expedite console messages

Show all headers | View raw

The "Disabled dynamic grace-period expediting" console message is
currently printed unconditionally.  This commit causes it to be
output only when it is impossible to switch between normal and
expedited grace periods, which was the original intent.
