The patch titled mm: remove unevictable's show_page_path has been removed from the -mm tree. Its filename was mm-remove-unevictables-show_page_path.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: remove unevictable's show_page_path From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx> Hugh Dickins reported show_page_path() is buggy and unsafe. because - lack dput() against d_find_alias() - don't concern vma->vm_mm->owner == NULL - lack lock_page() it was only for debugging, so rather than trying to fix it, just remove it now.
