   An update that has three 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 SP3 to version 8.4.4,
   providing many fixes and  enhancements.

   Changes included in the user land packages:

   * New drbd-proxy option "bwlimit"; allow proxy options
   on host level
   * crm-fence-peer: less cib polling, peer-alive
   detection using crmadmin, and other improvements
   * ocf ra: avoid too tight pacemaker driven recovery
   loop on failed promote, implement adjust_master_score
   parameter
   * drbdadm adjust now deals with IP-address changes
   correctly
   * Make sure old binary paths are still accessible.

   Changes included in the kernel modules:

   * Fix potential deadlock when concurrently fencing and
   establishing a connection
   * Fix potential distributed deadlock during verify or
   resync
   * Fix decoding of bitmap vli rle for device sizes > 64
   TB
   * Fix for deadlock when using automatic
   split-brain-recovery
   * Only fail empty flushes if no good data is reachable
   * Avoid to shrink max_bio_size due to peer
   re-configuration
   * Fix resume-io after reconnect with broken fence-peer
   handler
   * Fix too large bursts for very slow resync rates
   * Don't let application IO throttle resync to a stall
   * Fix a hole in the challenge-response implementation
   * Fix a theoretical IO deadlock (only triggers with
   unusual small AL i.e. 7)
   * Fix attaching to disks with fixed size external
   meta-data (bnc#833764)
   * Fix NULL pointer deref in module init error path
   (bnc#825657)
   * Fix a crash when the connection broke at a very exact
   point in time while a graceful disconnect executes
   * Support for REQ_DISCARD
   * Allow parallel promote/demote
   * Allow online changing of al-stripes and
   al-stripe-size with the resize command.
