From: Ryan Harper <ryanh at us.ibm.com> Rather than faking up some geometry, allow the backend to push the disk geometry via virtio pci config option. Keep the old geo code around for compatibility.

PCI, lguest and s390 can all only support 256-byte configuration space. So, this giant field broke just about everyone. Unfortunately, removing it is not so simple: we don't want to break old userspace, but we're going to want to re-use that part of the struct. So, modern users can #define VIRTIO_BLK_IDENTIFY_DEPRECATED to indicate that they know it's no longer in the config struct,

Latest virtio spec says the feature bit name is VIRTIO_BLK_F_FLUSH, VIRTIO_BLK_F_WCE is the legacy name. virtio blk header says exactly the reverse - fix that and update driver code to match.

Hello Rusty, sometimes it is useful to share a disk (e.g. usr). To avoid file system corruption, the disk should be mounted read-only in that case. This patch adds a new feature flag, that allows the host to specify, if the disk should be considered read-only.

Rusty, Jens, I need your opinion on the following patch. It seems to work, but I would like to get some feedback if this patch is the right approach: --- Currently virtio_blk assumes a 512 byte hard sector size. This can cause trouble / performance issues if the backing has a different block size (like a file on an ext3 file system formatted with 4k block size or a dasd device). Lets add a
