#     
#     Pull RCU fix from Paul McKenney:
#      "This brings the rcu_torture_read event trace into line with the new
#       trace tools by replacing this event trace's __field() with the
#       corresponding __array().
#     
#       Without this, the new trace tools will fail when presented wtih an
#       rcu_torture_read event trace, which is a regression from the viewpoint
#       of trace tools users"
