From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>
The kvfree_rcu() macro's single-argument form is deprecated. Therefore switch to the new kvfree_rcu_mightsleep() variant. 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.
