break_stripe_batch list didn't clear head_sh->batch_head. This was probably a bug. Also clear all R5_Overlap flags and if any were cleared, wake up 'wait_for_overlap'. This isn't always necessary but the worst effect is a little extra checking for code that is waiting on wait_for_overlap. Also, don't use wake_up_nr() because that does the wrong thing if 'nr' is zero, and it number of flags cleared doesn't strongly correlate with the number of threads to wake.
