Its filename was mm-page_owner-drop-redundant-page_owner-prefix-from-static-symbols.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Ye Liu Subject: mm/page_owner: drop redundant page_owner prefix from static symbols Date: Fri, 26 Jun 2026 10:45:45 +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.
