      Description

      When the old create proc interface was deprecated cksum_test was updated
      to use the new file operations table. Inadvertantly read was left as a capability
      without actually defining a function that the file would use when someone tried
      to read the file. This causes a kernel crash when cksum_test is read, though it
      can only be done by the root user.
