From: Rafał Miłecki <ra...@milecki.pl>
Kernel can report mount point as expired and when that happens mountd
unmounts it. It's still important to:
1) Cleanup directories
2) Call hotplug scripts
when device for such a mount disappears. Fix this by adding a new
EXPIRED status and checking it when block device disappears.
