Add a shortcut to the default map resource path, since fetching the size requires no address to be passed in, and thus no VMA to setup. Fixes: 3ad0876554caf ('xen/privcmd: add IOCTL_PRIVCMD_MMAP_RESOURCE')I don't think this addition is a reason to add a "Fixes:" tag. This is clearly new functionality.It could be argued that not allowing to query the resource size was a shortcoming of the original implementation, but a backport request to stable would be more appropriate than a fixes tag I think. Will drop on next version and add a backport request if you agree. Yes, please. Juergen Attachment:
