[PATCH rcu 0/8] kvfree_rcu() changes for v6.5

[Paul E. McKenney]

Hello!

This series contains updates for kvfree_rcu(), perhaps most notably
the removal of single-argument k{,v}free_rcu() in favor of the new-ish
k{,v}free_rcu_mightsleep().

1.	rcu/kvfree: Eliminate k[v]free_rcu() single argument macro,
	courtesy of "Uladzislau Rezki (Sony)".

2.	rcu/kvfree: Add debug to check grace periods.

3.	rcu/kvfree: Add debug check for GP complete for kfree_rcu_cpu
	list, courtesy of "Uladzislau Rezki (Sony)".

4.	rcu/kvfree: Invoke debug_rcu_bhead_unqueue() after checking
	bnode->gp_snap, courtesy of Zqiang.

5.	rcu/kvfree: Use consistent krcp when growing kfree_rcu() page
	cache, courtesy of Zqiang.

6.	rcu/kvfree: Do not run a page work if a cache is disabled,
	courtesy of "Uladzislau Rezki (Sony)".

7.	rcu/kvfree: Make fill page cache start from krcp->nr_bkv_objs,
	courtesy of Zqiang.

8.	rcu/kvfree: Make drain_page_cache() take early return if cache
	is disabled, courtesy of Zqiang.

						Thanx, Paul
