Message-ID: <20200624201200.GA28901@paulmck-ThinkPad-P72> (raw)

Hello!

This series contains kfree_rcu() updates.  Unless otherwise noted,
these are all courtesy of Uladzislau Rezki.

1.	Fix a kernel-doc warnings for "count", courtesy of Mauro Carvalho
	Chehab.

2.	rcu/tree: Keep kfree_rcu() awake during lock contention, courtesy
	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
