The raid bdev may receive IO requests after the raid layer invokes spdk_bdev_unregister function. This patch moves the raid_bdev->module->stop to the raid_bdev_destruct function. Then there will be no IO after the raid_bdev->module->stop is invoked. Below is a way to reproduce this issue: (1) create a malloc bdev sudo ./scripts/rpc.py bdev_malloc_create --name malloc0 128 4096 (2) create a concat bdev base on the malloc bdev sudo ./scripts/rpc.py bdev_raid_create --name concat0 \ --raid-level concat --base-bdevs malloc0 --strip-size-kb 4 (3) create a lvstore base on the concat bdev sudo ./scripts/rpc.py bdev_lvol_create_lvstore \ --cluster-sz 4194304 --clear-method unmap concat0 lvs0 (4) remove the concat bdev sudo ./scripts/rpc.py bdev_raid_delete concat0 In the step(4), the spdk app will crash because an IO request is sent to the concat bdev after the concat_stop is invoked.
