Changes in v2: patch 2 (blkif.h: Provide more complete documentation of the blkif interface.): o Mark backend device identification section as private to the backend driver. o Refer to docs/misc/vbd-interface.txt for the format of the virtual-device front-end node. o Correct field size for the virtual-device front-end node. patch 3 (blkif.h: Document the RedHat and Citrix blkif multi-page ring extensions.): o Correct node names for the RedHat/Amazon multi-ring extension. The previous patch mistakenly documented the now defunct FreeBSD extension. o Clarify the note on multi-page ring interoperability to indicate that identical ring parameters should be published to the XenStore for all supported schemes. v1 patch 4 (Deleted): o Remove patch that added the XEN_*_MAJOR definitions. patch 4 (blkif.h: Define and document the request number/size/segments extension.) o Bump __XEN_LATEST_INTERFACE_VERSION to 0x00040201 and use this version to guard the change to BLKIF_MAX_SEGMENTS_PER_REQUEST. -- Justin
