| |
Hi Wei,
commit ccc9d90a9a8b5 ("xenbus_client: Extend interface to support multi-page ring") addes a use of vmap in what is now xenbus_map_ring_valloc_hvm, and uses the VM_IOREMAP flag that is only really intended for implementing ioremap. Do you remember what the reason is that this flag was used?
