systems since ext3-based ldiskfs is not supported on big-endian
systems. This can be over-riden with "bigendian_extents" mount option.
+Severity : enhancement
+Bugzilla : 12749
+Description: The root squash functionality
+Details : A security feature, which is to prevent users from being able
+ to mount lustre on their desktop, run as root, and delete
+ all of the files in the filesystem. The goal is accomplished by
+ remapping user id (UID) and group id (GID) of the root user to
+ a UID and GID specified by the system administartor via Lustre
+ configuration management server (MGS). The functionality also
+ allows to specify sets of clients for which the remapping does
+ not apply.

+Severity : normal
+Bugzilla : 16860
+Description: Excessive recovery window
+Details : With AT enabled, the recovery window can be excessively long (6000+
+ seconds). To address this problem, we no longer use
+ OBD_RECOVERY_FACTOR when extending the recovery window (the connect
+ timeout no longer depends on the service time, it is set to
+ INITIAL_CONNECT_TIMEOUT now) and clients report the old service
+ time via pb_service_time.
+
+Severity : normal
+Bugzilla : 16522
+Description: Watchdog triggered on MDS failover
+Details : enable OBD_CONNECT_MDT flag when connecting from the MDS so that
+ the OSTs know that the MDS "UUID" can be reused for the same export
+ from a different NID, so we do not need to wait for the export to be
+ evicted
