[PATCH] rcu: Fix rcu_torture_read ftrace event

[Douglas RAILLARD]

From: Douglas Raillard <douglas.raillard@xxxxxxx>

Fix the rcutorturename field so that its size is correctly reported in
the text format embedded in trace.dat files. As it stands, it is
reported as being of size 1:

    field:char rcutorturename[8];   offset:8;       size:1; signed:0;
