McKenney" <paulmck@...nel.org>, Joel Fernandes <joel@...lfernandes.org>, linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 07/14] ext4/super: Rename kfree_rcu() to kfree_rcu_mightsleep() From: "Uladzislau Rezki (Sony)" <urezki@...il.com> The kfree_rcu() and kvfree_rcu() macros' single-argument forms are deprecated. Therefore switch to the new kfree_rcu_mightsleep() and kvfree_rcu_mightsleep() variants. 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.
