Subject[PATCH 5/8] mm/compaction: corret comment of cached migrate pfn update
Date
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.
