[PATCH] Reparsing on mountpoint boundary crossing

We have mountpoints underneath the share root. They have separate
quotas for each filesystem. This gives us something akin to
per-directory quota without actually having it. It makes the free-space
calculations correct, since they are re-requested upon reparse at that
point. Prior to this, you could not copy files into those mountpoints
directories if there was not enough space in the shares root.
