Then it doesn't seem that a new helper function is very useful! You'll just end up with alloc_vm_area() followed by open coding of requesting mapping of two grant references, won't you? A general function that did all that would be reasonable, and then I'd get rid of the special-case 'ring' functions. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
