We need this for other issues as well. f.e. to establish memory allocation policies for the page cache, tmpfs and various other needs. Look at mempolicy.h which defines a subset of what we need. Currently there is no way to specify a policy when invoking the page allocator or slab allocator. The policy is implicily fetched from the current task structure which is not optimal. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
