similar to: [Qemu-devel] [PATCH v6 12/12] virtio-blk: add x-data-plane=on|off performance feature

From: Nicholas Bellinger <nab at linux-iscsi.org> This patch changes virtio-scsi to use a new virtio_driver->scan() callback so that scsi_scan_host() can be properly invoked once virtio_dev_probe() has set add_status(dev, VIRTIO_CONFIG_S_DRIVER_OK) to signal active virtio-ring operation, instead of from within virtscsi_probe(). This fixes a bug where SCSI LUN scanning for both

I'm not reposting the drivers this time since they haven't changed significantly. See http://lguest.ozlabs.org/patches for the whole thing, from new-io.patch onwards). Changes since last version: - Switch to our own bus implementation, rather than relying on an implementation-specific bus to back this up. - Make virtio_config_ops much higher-level, don't assume layout of

Rusty, I have a mind to send this patches for the next merge window. Any input on this? This fixes the following virtio spec compliance issues: 1. on restore, drivers use device before setting ACKNOWLEDGE and DRIVER bits 2. on probe, drivers aren't prepared to handle config interrupts arriving before probe returns 3. on probe, drivers use device before DRIVER_OK it set Note that 1 is a
