Its filename was mm-reject-vmap-with-vm_flush_reset_perms.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: Christoph Hellwig Subject: mm: reject vmap with VM_FLUSH_RESET_PERMS Date: Sat, 21 Jan 2023 08:10:42 +0100 Patch series "cleanup vfree and vunmap". This little series untangles the vfree and vunmap code path a bit. This patch (of 10): VM_FLUSH_RESET_PERMS is just for use with vmalloc as it is tied to freeing the underlying pages.
