The patch titled Subject: dm-crypt: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN has been added to the -mm mm-unstable branch. Its filename is dm-crypt-use-arch_dma_minalign-instead-of-arch_kmalloc_minalign.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/dm-crypt-use-arch_dma_minalign-instead-of-arch_kmalloc_minalign.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Catalin Marinas <catalin.marinas@xxxxxxx> Subject: dm-crypt: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN Date: Mon, 12 Jun 2023 16:31:53 +0100 ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects alignment.
