The new_chunk fields of both struct mddev_s and struct mdp_superblock_1 are measured in bytes. However, in super_1_sync(), mddev->new_chunk is converted to sectors before it assigned to sb->new_chunk. This results in a too small number being stored in the in-memory image of the superblock which could confuse the reshape process.
