| |
stripe_add_to_batch_list() is better done in the loop in make_request instead of inside add_stripe_bio(). This is clearer and allows for storing the batch_head state outside the loop in a subsequent patch.
The call to add_stripe_bio() in retry_aligned_read() is for a read only and thus wouldn't have added the batch anyway.
No functional changes intended.
