Tomasz Zawadzki 0f5157377f lib/blob: merge EP of a clone when deleting a snapshot ... In general it is not possible to delete snapshot when there are clones on top of it. There is special case when there is just a single clone on top that snapshot. In such case the clone is 'merged' with snapshot. Unallocated clusters in clone, are filled with the ones in snapshot (if allocated there). Similar behavior should have occurred for extent pages. This patch adds the implementation for moving EP from snapshot to clone along with UT. The UT exposes the issue by allowing delete_blob to proceed beyond just unrecoverable snapshot blob.
