rcu: Several rcu_segcblist functions can be static
None of rcu_segcblist_set_len(), rcu_segcblist_add_len(), or rcu_segcblist_xchg_len() are used outside of kernel/rcu/rcu_segcblist.c. This commit therefore makes them static. Fixes: eda669a6a2c5 ("rcu/nocb: Atomic ->len field in rcu_segcblist structure") Signed-off-by: kbuild test robot <lkp@intel.com> [ paulmck: "Fixes:" updated per Stephen Rothwell feedback. ] Signed-off-by: Paul E.
