[PATCH rcu/dev -fixes 0/4]

[Joel Fernandes (Google)]

Hi,
Some of these patches would prevent breakage on PREEMPT_RT. I have marked them
as "rcu/dev fixes". Please consider applying for v5.8. The exceptions are 3/4
and 4/4 which some small clean-ups. Thanks!

Joel Fernandes (Google) (3):
rcu/tree: Keep kfree_rcu() awake during lock contention
rcu/tree: Skip entry into the page allocator for PREEMPT_RT
rcu/tree: Use consistent style for comments

Sebastian Andrzej Siewior (1):
rcu/tree: Avoid using xchg() in kfree_call_rcu_add_ptr_to_bulk()
