   An update that has two recommended fixes can now be
   installed. It includes one version update.

Description:


   This update updates the Distributed Replicated Block Device
   (DRBD)  component of SLES HAE 11 SP2 to version 8.4.2
   (FATE#313824, bnc#751135),  providing many fixes and
   improvements:

   * Fixed a race condition that could cause DRBD to go
   through a NetworkFailure state during disconnect
   (bnc#775930)
   * Fixed IO resuming after connection was established
   before fence peer handler returned
   * Fixed an issue in the state engine that could cause
   state lockup with multiple volumes
   * Write all pages of the bitmap if it gets moved during
   an online resize operation
   * Fixed a race condition in the disconnect code path
   that could lead to a BUG()
   * Fixed a write ordering problem on SyncTarget nodes
   for a write to a block that gets resynced at the same time.
   * Fixed a potential deadlock during restart of
   conflicting writes
   * Disable the write ordering method "barrier" by default
   * Removed a null pointer access when using
   on-congestion policy on a diskless device
   * In case of a graceful detach under IO load, wait for
   the outstanding IO
   * Reinstate disabling AL updates with invalidate-remote
   * Reinstate the 'disk-barrier no', 'disk-flushes no',
   and 'disk-drain no' switches
   * Support FLUSH/FUA bio flags
   * New option 'al-updates no' to disable writing
   transactions into the activity log.

   Please refer to the package change log for more details.
