[merged mm-stable] mm-page_owner-drop-redundant-page_owner-prefix-from-static-symbols.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/page_owner: drop redundant page_owner prefix from static symbols
has been removed from the -mm tree.  Its filename was
     mm-page_owner-drop-redundant-page_owner-prefix-from-static-symbols.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/page_owner: drop redundant page_owner prefix from static symbols
Date: Tue, 14 Jul 2026 09:51:06 +0800

All of these symbols are file-scoped (static) in page_owner.c, so the
page_owner_ prefix is pure noise.  Rename them to shorter, still-clear
names:

  page_owner_stack_op      -> stack_op
  page_owner_stack_open    -> stack_open
  page_owner_stack_fops    -> stack_fops
  page_owner_pages_threshold -> pages_threshold
  page_owner_threshold_get -> threshold_get
  page_owner_threshold_set -> threshold_set
  page_owner_threshold_fops -> threshold_fops

No functional change.
