Subject: [v2 PATCH 0/2] enhance kfree_rcu() throughput

Here we go with V2 version of the "support kfree_bulk() interface in
kfree_rcu()" patchest. Apart of that there is one more, it just adds
a trace event for kfree_bulk() call.

Boths patches are based on "dev.2020.01.10a" branch of the linux-rcu.git

V1 -> V2:
   - fix and support debugobjects;
   - updated the commit message of [1]. Added test results
     of CONFIG_SLAB / CONFIG_SLUB configurations together
     with recent new parameter kfree_vary_obj_size=1;
   - add more comments.

Rezki (Sony) (2):
[1]  rcu/tree: support kfree_bulk() interface in kfree_rcu()
[2]  rcu/tree: add a trace invoke event of the kfree_bulk()
