Kernel Support for Stackable File Systems
Josef Sipek, Yiannis Pericleous, Erez Zadok · 2007
Although it is now possible to use stackable (layered) file systems in Linux, there are several issues that should be addressed to make stacking more reliable and effi-cient. To support stacking properly, some changes to the VFS and VM subsystems will be required. In this paper, we discuss some of the issues and solutions pro-posed at the Linux Storage and Filesystems workshop in February 2007, our ongoing work on stacking sup-port for Linux, and our progress on several particular stackable file systems. 1
