Subject: keep ->cleaning list in order.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=0444a97d582d38471a278efc8ba59165c065ef57;p=LaFS.git

keep ->cleaning list in order.

As we processes blocks from the segment in order, it is best
to keep them in order for later processing.
They will be sorted again when being added to a cluster,
but the more we help here, the better.
