Subject: [PATCH 1/2] mm: slab: fix comment for ARCH_KMALLOC_MINALIGN
Date: Thu, 28 Apr 2022 17:59:39 +0200	[thread overview]
Message-ID: <fe1ca7a25a054b61d1038686d07569416e287e7b.1651161548.git.andreyknvl@google.com> (raw)

From: Andrey Konovalov <andreyknvl@google.com>

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.
