[merged mm-stable] selftests-mm-mark-file-local-symbols-of-pagemap_ioctlc-static.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: selftests/mm: mark file-local symbols of pagemap_ioctl.c static
has been removed from the -mm tree.  Its filename was
     selftests-mm-mark-file-local-symbols-of-pagemap_ioctlc-static.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: "Zenghui Yu (Huawei)" <zenghui.yu@linux.dev>
Subject: selftests/mm: mark file-local symbols of pagemap_ioctl.c static
Date: Tue, 8 Sep 2026 21:43:14 +0800

The file-scope variables (pagemap_fd, uffd, page_size, hpage_size and
progname) and most functions of the pagemap_ioctl test are only used
locally, but lack the static storage class.  Mark them static so that the
compiler can catch accidental outer references.
