Its filename was optee-remove-vma-linked-list-walk.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: "Matthew Wilcox (Oracle)" Subject: optee: remove vma linked list walk Date: Tue, 6 Sep 2022 19:48:55 +0000 Use the VMA iterator instead. Change the calling convention of __check_mem_type() to pass in the mm instead of the first vma in the range.
