[merged mm-stable] mm-mlock-rename-mlock_future_check-to-mlock_future_ok.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/mlock: rename mlock_future_check() to mlock_future_ok()
has been removed from the -mm tree.  Its filename was
     mm-mlock-rename-mlock_future_check-to-mlock_future_ok.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: mm/mlock: rename mlock_future_check() to mlock_future_ok()
Date: Mon May 22 01:52:10 PM PDT 2023

It is felt that the name mlock_future_check() is vague - it doesn't
particularly convey the function's operation.  mlock_future_ok() is a
clearer name for a predicate function.
