# HG changeset patch # User Ian Campbell <ian.campbell@xxxxxxxxxx> # Date 1286892401 -3600 # Node ID 15c4f1cde006e6d8309eff86a99b609c4c1f090a # Parent a577eeeb43690b9df6be4789ced815e0c8e4cf13 libxc: use correct size of struct xen_mc We want the size of the struct not the pointer (although rounding up to page size in lock_pages probably saves us).
