    ocfs2: Don't walk off the end of fast symlinks.
    
    [Pulled from fixes before it was pushed to mainline]
    
    ocfs2 fast symlinks are NUL terminated strings stored inline in the
    inode data area.  However, disk corruption or a local attacker could, in
    theory, remove that NUL.  Because we're using strlen() (my fault,
    introduced in a731d1 when removing vfs_follow_link()), we could walk off
    the end of that string.
