I would rather approach this with great care, please do not just revert, as to me that looks like a huge churn, and it well not remove the incorrect history. Lets focus on clearly identifying the list of rXXXXXX by expanding your list of r316370, r317095, r324394 until we have them. Then we need to verify we are not getting anything that has already been cleaned up by someone else. (Also a concern with just trying to revert this patch). -- Rod Grimes rgrimes@freebsd.org
