rcu: Make _batches_completed() functions return unsigned long
Long ago, the various ->completed fields were of type long, but now are unsigned long due to signed-integer-overflow concerns. However, the various _batches_completed() functions remained of type long, even though their only purpose in life is to return the corresponding ->completed field. This patch cleans this up by changing these functions' return types to unsigned long. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
