| Subject: mm/thp: drop follow_devmap_pmd() default stub |
| Date: Mon, 29 Sep 2025 11:46:43 +0100 |
| |
| follow_devmap_pmd() has already been dropped by the commit fd2825b0760a |
| ("mm/gup: remove pXX_devmap usage from get_user_pages()"). The fallback |
| stub in the header which is now redundant, can be dropped off as well. |
