Basic validation for the recompute-xattr-total ioctl through the totl-delta-inject ioctl. Takes a few different corrective actions that are plausible - simple drifted values, and a stray orphan totl. The test validates that the kmod dmesg output matches what was expected since that's our proof that repair happened, but the actual warnings are filtered from logs during test to not fail our test case otherwise.

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
