The following are not used outside the unit they are
declared in, so make them static to avoid the following
sparse warnings:
kernel/rcu/rcu_segcblist.c:91:6: warning: symbol 'rcu_segcblist_set_len' was not declared. Should it be static?
kernel/rcu/rcu_segcblist.c:107:6: warning: symbol 'rcu_segcblist_add_len' was not declared. Should it be static?
kernel/rcu/rcu_segcblist.c:137:6: warning: symbol 'rcu_segcblist_xchg_len' was not declared. Should it be static?
