Branch b1_4

Branch b1_4
Description: Unusual file access patterns on the MDS may result in inode
             data being lost in very rare circumstances.
Details    : Bad interaction between the ea-in-inode patch and the "no-read"
             code in the 2.6 kernel caused the inode and/or EA data not to
             be read from disk, causing single-file corruption.
