The following patches were made over Linus's tree and fix an issue where windows guests will send iovecs with offset/lengths that result in IOs that are not aligned to 512. The LIO layer will then send them to Linux's FS/block layer but it requires 512 byte alignment, so depending on the FS/block driver being used we will get IO errors or hung IO. The following patches have vhost-scsi

The virtqueue_add_buf function has two limitations: 1) it requires the caller to provide all the buffers in a single call; 2) it does not support chained scatterlists: the buffers must be provided as an array of struct scatterlist. Because of these limitations, virtio-scsi has to copy each request into a scatterlist internal to the driver. It cannot just use the one that was prepared by the

Further cleanup of the hv drivers: 1) Cleanup the reference counting mess for both stor and net devices. 2) Handle all block devices using the storvsc driver. 3) Accomodate some host side scsi emulation bugs. 4) In case of scsi errors off-line the device. Regads, K. Y

This is a resend of the patches yet to be applied. This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup error handling in the vmbus_probe() and vmbus_child_device_register() functions. Fixed a bug in the probe failure path as part of this cleanup. 2) The Windows
