Hi all: This series tries to support batched IOTLB updating vhost-vdpa. Currently vhost-vdpa accepts userspace mapping via IOTLB API, and it can only forward one mapping to IOMMU or device through IOMMU API or dma_map(). Though set_map() is designed to have the capability to pass an rbtree based mapping to vDPA device, it's still be called at least once for each VHOST_IOTLB_UPDATE or

This still causes corruption issues for people so don't try to use in production please. Posting to expedite debugging. This adds infrastructure required for supporting multiple ring formats. The idea is as follows: we convert descriptors to an independent format first, and process that converting to iov later. Used ring is similar: we fetch into an independent struct first, convert that to

This intentionally leaves "fixup" changes separate - hopefully that is enough to fix vhost-net crashes reported here, but it helps me keep track of what changed. I will naturally squash them later when we are done. This adds infrastructure required for supporting multiple ring formats.
