Subject: [PATCH v2 04/14] lib/test_vmalloc.c: Rename kvfree_rcu() to kvfree_rcu_mightsleep()

From: "Uladzislau Rezki (Sony)" <urezki@...il.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.
