[Andrew Morton]

The quilt patch titled
     Subject: selftests: make use of GUP_TEST_FILE macro
has been removed from the -mm tree.  Its filename was
     selftests-make-use-of-gup_test_file-macro.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

Subject: selftests: make use of GUP_TEST_FILE macro
Date: Thu, 9 Jun 2022 16:32:17 -0400

Commit 17de1e559cf1 ("selftests: clarify common error when running
gup_test") had most of its hunks dropped due to a conflict with another
patch accepted into Linux around the same time that implemented the same
behavior as a subset of other changes.

However, the remaining hunk defines the GUP_TEST_FILE macro without making
use of it.  This patch makes use of the macro in the two relevant places.

Furthermore, the above mentioned commit's log message erroneously
describes the changes that were dropped from the patch.

This patch corrects the record.
