Linux file undelete

• Student: Samir Raizade (2007).
• Purpose: Implement file undelete in Linux.
• Method: Change the implementation of unlink to add the affected inode and its path name to an in-core list, without decrementing the usage count of the inode. Start a timer that on expiration completes the deletion. Provide an undelete system call.
• What the student learned
  1. Linux VFS layer.
  2. Linux timer structures.
