Rob N 917ff75e95 vdev_disk: don't touch vbio after its handed off to the kernel ... After IO is unplugged, it may complete immediately and vbio_completion be called on interrupt context. That may interrupt or deschedule our task. If its the last bio, the vbio will be freed. Then, we get rescheduled, and try to write to freed memory through vbio->. This patch just removes the the cleanup, and the corresponding assert. These were leftovers from a previous iteration of vbio_submit() and were always "belt and suspenders" ops anyway, never strictly required. Sponsored-by: Klara, Inc.
