A file-backed namespace has no block device, so\nreq->ns->bdev is NULL and bdev_is_zoned() dereferences it, oopsing.\n\nThe I/O command set is selected by the host-supplied CSI field and the\ncommand is routed here whenever CONFIG_BLK_DEV_ZONED is enabled,\nindependent of the namespace backing type, so any file-backed namespace\nis exposed.\n\nReject the command with Invalid Field when the namespace is not backed\nby a block device.",
