Yet another major shrinker API evolution in v6.6-rc4-53-gc42d50aefd17. The struct shrinker now has to be dynamically allocated. This is purposely a backwards incompatible break. We add another KC_ wrapper around the new shrinker_alloc() and move some initialization around to make this as much as possible low impact, but compatible with the old APIs through substitution.

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
