-               sector_div(bm_blocks,
-                          bitmap->mddev->bitmap_info.chunksize >> 9);

+                          (bitmap->mddev->bitmap_info.chunksize >> 9));

If my patch would be accepted, I will send v2 patch including above lines.

Please send v2 of the patch. Please also CC Guoqing in v2.
