This series reworks the quotaoff algorithm to eliminate a log reservation deadlock vector. v2 is primarily a rebase/repost of v1. Note that this conflicts with the recently posted append ioend cleanup, but this series is still based on for-next. I can post another rebased series if either of these progress.
