[PATCH 5/6] powerpc/mm: make vmemmap_populate_compound_pages() static
From: Muchun Song <hidden>
Date: 2026-09-13 08:41:08
Also in:
linux-mm, lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
vmemmap_populate_compound_pages() is no longer used outside radix_pgtable.c. Make it static and drop the unused dev_pagemap argument from its only remaining caller to simplify the code.
