# HG changeset patch # User Ian Campbell <ian.campbell@xxxxxxxxxx> # Date 1287650255 -3600 # Node ID 19f7acc52f243f91f3ba539b0475dafbb0546ba0 # Parent 0d9e118f705231b0ac88b9ae98f996e0e62152c7 libxc: switch page offlining interfaces to hypercall buffers There is no need to lock/bounce minfo->pfn_type in init_mem_info since xc_get_pfn_type_batch() will take care of that for us.
