Subject: [PATCH] x86/mm: use PAGE_ALIGNED instead of IS_ALIGNED
Date: Thu, 26 May 2022 22:20:39 +0800 [thread overview]
Message-ID: <20220526142038.1582839-1-bh1scw@gmail.com> (raw)
From: Fanjun Kong <bh1scw@gmail.com>
The <linux/mm.h> already provides the PAGE_ALIGNED macro. Let's
use this macro instead of IS_ALIGNED and passing PAGE_SIZE directly.
