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.
