Urgent RCU pull request for v6.3

Browse source 
This commit 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 commit, 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.
