Subject: mm/page_alloc: replace flag check with PageHWPoison() in check_new_page_bad()
Date: Thu, 20 Mar 2025 14:33:46 +0800
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.
