From cae16f2c2e11c60c888715f4d98c12740683d6a2 Mon Sep 17 00:00:00 2001 From: "Uladzislau Rezki (Sony)" Date: Wed, 1 Feb 2023 16:08:10 +0100 Subject: [PATCH] tracing: Rename kvfree_rcu() to kvfree_rcu_mightsleep() 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.
