Subject: [PATCH] mlxsw: core: Switch to kvfree_rcu() API
Date: Wed, 15 Dec 2021 12:18:43 +0100	[thread overview]
Message-ID: <20211215111845.2514-7-urezki@gmail.com> (raw)
In-Reply-To: <20211215111845.2514-1-urezki@gmail.com>

Instead of invoking a synchronize_rcu() to free a pointer
after a grace period we can directly make use of new API
that does the same but in more efficient way.
