Subject: mm/compaction: correct comment of cached migrate pfn update
Date: Fri, 4 Aug 2023 19:04:51 +0800
Commit e380bebe47715 ("mm, compaction: keep migration source private to a
single compaction instance") moved update of async and sync
compact_cached_migrate_pfn from update_pageblock_skip to
update_cached_migrate but left the comment behind. Move the relevant
comment to correct this.
