Gaurav Menghani
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 ).
- 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
- Code
