This isn't functionality the XenServer makes use of so I've not tested these with paging in use. Changes since v1: - Don't change PRIVCMD_MMAPBATCH (except to #define a constant for the error). It's broken and not really fixable sensibly and libxc will use V2 if it is available. - Return -ENOENT if all failures were -ENOENT. - Clear arg->err on success (libxc expected this). I think this should probably get a "Tested-by" Andres or someone else who uses paging before being applied. David
