Subject: [PATCH 5/8] iommu/vt-d: Remove initialization for dynamically heap-allocated rcu_head
Date: Tue, 27 Feb 2024 10:14:38 +0800 [thread overview]
Message-ID: <20240227021441.50434-6-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20240227021441.50434-1-baolu.lu@linux.intel.com>
From: Tina Zhang <tina.zhang@intel.com>
The rcu_head structures allocated dynamically in the heap don't need any
initialization. Therefore, remove the init_rcu_head().
