This patch misses modifications to functions raid1_alloc_init_r1buf() and
raid10_alloc_init_r10buf(). They will be included with other suggestions in v2.


  static struct r1bio *raid1_alloc_init_r1buf(struct r1conf *conf)
  {
         struct r1bio *r1bio = mempool_alloc(&conf->r1buf_pool, GFP_NOIO);
-       struct resync_pages *rps;
+       struct resync_folio *rfs;
         struct bio *bio;
         int i;


  static struct r10bio *raid10_alloc_init_r10buf(struct r10conf *conf)
  {
         struct r10bio *r10bio = mempool_alloc(&conf->r10buf_pool, GFP_NOIO);
-       struct rsync_pages *rp;
+       struct resync_folio *rf;
         struct bio *bio;
         int nalloc;
         int i;
