Subject: [PATCH v2 08/14] rcuscale: Rename kfree_rcu() to kfree_rcu_mightsleep()

From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>

The kfree_rcu() and kvfree_rcu() macros' single-argument forms are
deprecated.  Therefore switch to the new kfree_rcu_mightsleep() and
kvfree_rcu_mightsleep() variants. The goal is to avoid accidental use
of the single-argument forms, which can introduce functionality bugs in
atomic contexts and latency bugs in non-atomic contexts.
