Mount option parsing runs early enough that the rest of the option read/write serialization infrastructure isn't set up yet. The quorum_heartbeat_timeout_ms mount option tried to use a helper that updated the stored option but it wasn't initialized yet so it crashed. The helper was really only to have the option validity test in one place. It's reworked to only verify the option and the actual setting is left to the callers.

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
