One Line Summary

This presentation will be of interest to system-administrators, kernel-developers, and any end users wanting to know more about this exciting feature. This presentation is aimed at seeking feedback to enrich the implementation and enhance the feature set.

Abstract

I will describe a VFS feature, that provides the ability to create a virtual file using parts and pieces of existing files. This feature enables the expansion of a file across filesystems, by mapping files on different filesystems into its address space. We have a working prototype of this feature. A patch towards which is already submitted to the VFS community requesting comments. The RFC can be found at http://permalink.gmane.org/gmane.linux.file-systems/73179. In this presentation, I will outline the feature and our reference implementation.
