From: Baolin Wang Date: Wed, 21 Jun 2023 08:14:28 +0000 (+0800) Subject: mm: page_alloc: use the correct type of list for free pages X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1bf61092bc90a9054d01cfdf35b42c1bf6fe47c7;p=linux.git mm: page_alloc: use the correct type of list for free pages Commit bf75f200569d ("mm/page_alloc: add page->buddy_list and page->pcp_list") introduces page->buddy_list and page->pcp_list as a union with page->lru, but missed to change get_page_from_free_area() to use page->buddy_list to clarify the correct type of list for a free page.
