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

This is a subject that came up in the virtio BOF session at OLS. I decided to go forward and implement something that I like, based on the latest virtio proposal at the time, which was draft III. It's not a drop-in replacement, because it's missing a host implementation. I first started my own, which is not done yet, but wanted to do one for lguest and one for emulated PCI next. It's

Also do you think you would be able to merge the driver (corresponding v4 patch follows) in the 3.2 merge window that seems to have just opened?

Rusty, I have a mind to include this patchset for this 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
