From 8cf9e1210adf49cd83d11e2b1984540cf0e0be71 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Thu, 28 Apr 2022 17:59:39 +0200 Subject: [PATCH] mm: slab: fix comment for ARCH_KMALLOC_MINALIGN The comment next to the ARCH_KMALLOC_MINALIGN definition says that ARCH_KMALLOC_MINALIGN can be defined in arch headers. This is incorrect: it's actually ARCH_DMA_MINALIGN that can be defined there. Fix the comment.
