That would be a spec violation though, even if it happens to work on current QEMU. The spec says: A driver MUST NOT create a descriptor chain longer than the Queue Size of the device. What prompted this patch? Do we ever encounter this

DAX is explained in detail here: https://lwn.net/Articles/610174/ This patch adds support to supermin for using a DAX root filesystem. The corresponding libguestfs patches will be posted shortly once I've tested them a bit more. This requires qemu >= 2.6. Unfortunately it's not really a win for a few reasons: - Requires enabling ACPI, which slows everything down by hundreds of

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just
