Make sure that the orphan scanners can see deletions after forced unmounts by waiting for reclaim_open_log_tree() to run on each mount; and waiting for finalize_and_start_log_merge() to run and not find any finalized trees. Do this by adding two new counters: reclaimed_open_logs and log_merge_no_finalized and fixing the orphan-inodes test to check those before waiting for the orphan scanners to complete.

Introduction
scoutfs is a clustered in-kernel Linux filesystem designed to support large archival systems. It features additional interfaces and metadata so that archive agents can perform their maintenance workflows without walking all the files in the namespace. Its cluster support lets deployments add nodes to satisfy archival tier bandwidth targets.
The design goal is to reach file populations in the trillions, with the archival bandwidth to match, while remaining operational and responsive.
Highlights of the design and implementation include:
- Fully consistent POSIX semantics between nodes
- Atomic transactions to maintain consistent persistent structures
- Integrated archival metadata replaces syncing to external databases
- Dynamic seperation of resources lets nodes write in parallel
- 64bit throughout; no limits on file or directory sizes or counts
- Open GPLv2 implementation
