Chris Kirby 4adcbf8a35 Only provide direct_IO method for platforms where we support it
This was causing some interesting issues because the vfs code
makes decisions based on the existence of the method while the
read/write iterators ignore the IOCB_DIRECT flag.

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
