Server Side Advise and Hinting

Introduction

Server Side Advise and Hinting introduces new APIs and utilities to provide information about access patterns of Lustre files to improve performance. This is similar to fadvise64_64 or posix_fadvise, but with the ability to pass information to the remote storage side. This is a new feature for Lustre 2.9
