Subject: [PATCH 0/2 v3] EXT4: Secure Delete

This patch set implements secure delete for ext4.  New
flags have been added to ext4_free_blocks and ext4_delete_entry
that cause the data blocks and directory entries to be
zeroed before they are released.  Files that have the 
secure remove attribute flag on will have their data and
directory entries zeroed when they are deleted.

Allison Henderson (2):
  EXT4: Secure Delete: Zero out file data
  EXT4: Secure Delete: Zero out files directory entry
