Commit e022864 introduced a regression for kernels which are built with CONFIG_DEBUG_PREEMPT. The use of CPU_SEQID in a preemptible context causes zio_nowait() to trigger the BUG. Since CPU_SEQID is simply being used as a random index the usage here is safe. To resolve the issue preempt is disable while calling CPU_SEQID.
