of Joel Fernandes.
3. rcu/tree: Skip entry into the page allocator for PREEMPT_RT,
courtesy of Joel Fernandes.
4. rcu/tree: Repeat the monitor if any free channel is busy.
5. rcu/tree: Make debug_objects logic independent of rcu_head,
courtesy of Joel Fernandes.
6. rcu/tree: Simplify KFREE_BULK_MAX_ENTR macro.
7. rcu/tree: Move kfree_rcu_cpu locking/unlocking to separate
functions.
8. rcu/tree: Use static initializer for krc.lock, courtesy of
Sebastian Andrzej Siewior.
9. rcu/tree: cache specified number of objects.
10. rcu/tree: Maintain separate array for vmalloc ptrs.
11. rcu/tiny: support vmalloc in tiny-RCU.
12. Rename *_kfree_callback/*_kfree_rcu_offset/kfree_call_*.
13. mm/list_lru.c: Rename kvfree_rcu() to local variant.
14. Introduce 2 arg kvfree_rcu() interface.
15. Support reclaim for head-less object.
16. Introduce single argument kvfree_rcu() interface.
17. lib/test_vmalloc.c: Add test cases for kvfree_rcu().
Thanx, Paul
