[PATCH 6.1 168/303] tracing: Rename kvfree_rcu() to kvfree_rcu_mightsleep()

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Uladzislau Rezki (Sony)" <[email protected]>

[ Upstream commit cae16f2c2e11c60c888715f4d98c12740683d6a2 ]

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.
