Subject: [PATCH 01/13] rcu/kvfree: Add kvfree_rcu_mightsleep() and kfree_rcu_mightsleep()
Date: Wed, 1 Feb 2023 16:08:07 +0100 [thread overview]
Message-ID: <20230201150815.409582-2-urezki@gmail.com> (raw)
In-Reply-To: <20230201150815.409582-1-urezki@gmail.com>
These two macroses will replace single-argument k[v]free_rcu() ones.
By adding an extra _mightsleep prefix we can avoid of situations when
someone intended to give a second argument but forgot to do it in a
code where sleeping is illegal.
