I do understand your point of view, and I can see how libUIO navigates sysfs from userspace to figure out what's there. Unfortunately I am not in a position to mandate the inclusion of sysfs in our deployment, and Linux UIO has a dependency on sysfs to be usable. I had hoped to stay within the confines of the mainline, but for now we'll have to tolerate a local patch. Earl
