[merged mm-stable] mm-oom_kill-use-mmu_notify_clear-in-__oom_reap_task_mm.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/oom_kill: use MMU_NOTIFY_CLEAR in __oom_reap_task_mm()
has been removed from the -mm tree.  Its filename was
     mm-oom_kill-use-mmu_notify_clear-in-__oom_reap_task_mm.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/oom_kill: use MMU_NOTIFY_CLEAR in __oom_reap_task_mm()
Date: Fri, 27 Feb 2026 21:08:36 +0100

In commit 7269f999934b ("mm/mmu_notifier: use correct mmu_notifier events
for each invalidation") we converted all MMU_NOTIFY_UNMAP to
MMU_NOTIFY_CLEAR, except the ones that actually perform munmap() or
mremap() as documented.

__oom_reap_task_mm() behaves much more like MADV_DONTNEED.  So use
MMU_NOTIFY_CLEAR as well.

This is a preparation for further changes.
