Hello, This patchset tries to update the vhost-user protocol to make it support special memory mapping required in case of Xen hypervisor.
The first patch is mostly cleanup and second one introduces a new xen specific feature. V2->V3: - Remove the extra message and instead update the memory regions to carry additional data. - Drop the one region one mmap relationship and allow back-end to map only parts of a region at once, required for Xen grant mappings. - Additional cleanup patch 1/2. V1->V2: - Make the custom mmap feature Xen specific, instead of being generic. - Clearly define which memory regions are impacted by this change. - Allow VHOST_USER_SET_XEN_MMAP to be called multiple times. - Additional Bit(2) property in flags.
