kvfree_rcu: Use [READ/WRITE]_ONCE() macros to access to nr_bkv_objs nr_bkv_objs is a count of the objects in the kvfree_rcu page cache. Accessing it requires holding the ->lock. Switch to READ_ONCE() and WRITE_ONCE() macros to provide lockless access to this counter. This lockless access is used for the shrinker.
