Two different clients can write delta's for totl indexes at the same time, recording their changes. When merged, a reader should apply both in order, and only once. To do so, the seq determines whether the delta has been applied already. The code fails to update the seq while walking the trees for deltas to apply. Subsequently, when processing subsequent trees, it could re-process deltas already applied. In case of a large negative delta (e.g. removal of large amounts of files), the totl value could become negative, resulting in quota lockout. The fix is simple: advance the seq when reading partial delta merges to avoid double counting. Signed-off-by: Auke Kok <auke.kok@versity.com>
