On 11.01.21 16:29, Roger Pau Monne wrote: Allow issuing an IOCTL_PRIVCMD_MMAP_RESOURCE ioctl with num = 0 and addr = 0 in order to fetch the size of a specific resource. 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. Juergen Attachment:
