[PATCH tip/core/rcu 15/24] rcutorture: Remove redundant initialization to zero

From: Paul E. McKenney
Date: Tue Apr 12 2016 - 11:45:47 EST


The current code initializes the global per-CPU variables
rcu_torture_count and rcu_torture_batch to zero. However, C does this
initialization by default, and explicit initialization of per-CPU
variables now needs a different syntax if "make tags" is to work.
This commit therefore removes the initialization.
