A request that was partially completed, an ESE read of a\nnot-yet-allocated track returns fewer bytes than requested, and then\nrecovered through the ERP chain loses its partial-completion length.\n__dasd_cleanup_cqr() then sees proc_bytes == 0 and completes the whole\nrequest instead of requeueing the remainder, silently returning zeroed\ndata for the part that was never read.\n\nCarry
