People:

Synopsis:

The JOS filesystem is a bare-bones filesystem, which can be improved upon by adding
features of a contemporary filesystems. We propose implementing the following
features to extend the JOS filesystem:

- Journaled Soft Updates
(Dr. Marshall Kirk McKusick's paper on 
Journaled Soft Updates http://www.mckusick.com/publications/suj.pdf ).
- A fsck process to check for the File System consistency
- Supporting files > 4 MiB in size
- Adding meta-data to the File struct such as permission bits, owner id, group id 
for the purpose of ACLs

Deliverables
- Code
