Subject: [PATCH v6 09/17] dm-crypt: Use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
Date: Wed, 31 May 2023 16:48:28 +0100 [thread overview]
Message-ID: <20230531154836.1366225-10-catalin.marinas@arm.com> (raw)
In-Reply-To: <20230531154836.1366225-1-catalin.marinas@arm.com>
ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects
alignment.
