Subject: [PATCH] mm/page_alloc: Replace flag check with PageHWPoison() in check_new_page_bad()
Date: Thu, 20 Mar 2025 14:33:46 +0800 [thread overview]
Message-ID: <20250320063346.489030-1-ye.liu@linux.dev> (raw)
From: Ye Liu <liuye@kylinos.cn>
This patch replaces the direct check for the __PG_HWPOISON flag with
the PageHWPoison() macro, improving code readability and maintaining
consistency with other parts of the memory management code.
