Object list cache does not take too much memory, so reclaiming seems
unnecessary, but there's a problem:
Objects belonging to a deleted VDI does not exist any more, but the
associated entries still stay in the cache list, so if a recovery
happens, sheep would try to recovery these objects and of cause this
would cause many object recovery failure, and waste resource.
levin li (4):
sheep: notify VDI deletion to all nodes when deleting a VDI
object list cache: put all the cache entry into a list
object list cache: reclaim object list cache when receiving a
deletion event.
farm: comment why we can't remove objlist entry while deleting object
