The quilt patch titled
Subject: fs/proc/task_mmu: hide unused pagemap_scan_backout_range() function
has been removed from the -mm tree. Its filename was
fs-proc-task_mmu-implement-ioctl-to-get-and-optionally-clear-info-about-ptes-fix-3.patch
This patch was dropped because it was folded into fs-proc-task_mmu-implement-ioctl-to-get-and-optionally-clear-info-about-ptes.patch

Subject: fs/proc/task_mmu: hide unused pagemap_scan_backout_range() function
Date: Wed, 27 Sep 2023 08:02:23 +0200
This function has two callers, each of which are hidden behind an #ifdef:
fs/proc/task_mmu.c:2022:13: error: 'pagemap_scan_backout_range' defined but not used [-Werror=unused-function]
Add another conditional to check for both options to avoid the
unused-function warning.
