From eb56a4cbc3ea348dc07fbe82531c27cce83df3b9 Mon Sep 17 00:00:00 2001 From: "Joel Fernandes (Google)" Date: Fri, 10 Mar 2023 01:18:12 +0000 Subject: [PATCH] mac802154: Rename kfree_rcu() to kvfree_rcu_mightsleep() The k[v]free_rcu() macro's single-argument form is deprecated. Therefore switch to the new k[v]free_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. The callers are holding a mutex so the context allows blocking. Hence using the API with a single argument will be fine, but use its new name. There is no functionality change with this patch.
