HI Guys, Why is the below call needed in the function chunk_aligned_read() align_bi = bio_clone_mddev(raid_bio, GFP_NOIO, mddev); Why do we need to create a clone of the bio passed to chunk_aligned_read(mddev_t *mddev, struct bio * raid_bio) ?? -- Best Regards, Anuj Goel Experimental Computer Science Lab Stony Brook University.
