Subject: [PATCH] iommu/fsl_pamu: Simplify IOVA cache allocation with KMEM_CACHE() in fsl_pamu_domain.c
Date: Tue, 27 Feb 2024 17:08:25 +0800
Message-Id: <20240227090826.82475-1-liucong2@kylinos.cn>
Precedence: bulk

Content-Transfer-Encoding: 8bit

Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.
