mm/vmscan: make the annotations of refaults code at the right place
After patch "mm/workingset: prepare the workingset detection infrastructure for anon LRU", we can handle the refaults of anonymous pages too. So the annotations of refaults should cover both of anonymous pages and file pages. Link: https://lkml.kernel.org/r/20220813080757.59131-1-yang.yang29@zte.com.cn Fixes: 170b04b7ae4963 ("mm/workingset: prepare the workingset detection infrastructure for anon LRU") Signed-off-by: Yang Yang <yang.yang29@zte.com.cn> Signed-off-by: CGEL ZTE <cgel.zte@gmail.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Vlastimil Babka <vbabka@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
