It would be nice to see some reports on the stability on this, one way or the other. Next move is to clean up __clone_and_map the rest of the way. Thanks for your merge. Not easy, hmm? The mainline bio changes generated a bunch of tracking work, but they are sensible changes so no regrets (the bogus endio bytes parameter and int return are gone). Now... it appears to me that bi_size is an entirely redundant field, so while we are turfing bio junk out...
