Description: don't use GFP_* in generic Lustre code.
Details    : Use cfs_alloc_* functions and CFS_* flags for code portability.

To improve performance, disable most logging (for debug purposes)
by default.  VFSTRACE, RPCTRACE, and DLMTRACE are now off by
default, and HA includes contains fewer messages.

Clarify watchdog timer units.

Bugzilla   : 11684
Description: Added D_NETTRACE for recording network packet history
	     (initially only for ptllnd).  Also a separate userspace
	     ptllnd facility to gather history which should really be
	     covered by D_NETTRACE too, if only CDEBUG recorded history in
	     userspace.

Description: Mounting a Lustre file system on a node running as an OST could
             lead to deadlocks
Details    : OSTs now allocate memory needed to write out data at
             startup, instead of when needed, to avoid having to
             allocate memory in possibly low memory situations.
             Specifically, if the file system is mounted on on OST,
             memory pressure could force it to try to write out data,
             which it needed to allocate memory to do.  Due to the low
             memory, it would be unable to do so and the node would
             become unresponsive.
b=6514, b=5137

Description: Addition of lconf --service command line option
Details    : lconf now accepts a '--service <arg>' option, which is
             shorthand for 'lconf --group <arg> --select <arg>=<hostname>'
b=7015

Description: Failover mode is now the default for OSTs.
Details    : By default, OSTs will now run in failover mode.  To return to
             the old behaviour, add '--failout' to the lmc line for OSTs.
b=6101

Description: Health checks are now provided for MDS and OSTs
Details    : Additional detailed health check information on MSD and OSTs
             is now provided through the procfs health_check value.
b=1693

Description: Disk fragmentation on the OSTs could eventually cause slowdowns
             after numerous create/delete cycles
Details    : The ext3 inode allocation policy would not allocate new inodes
             very well on the OSTs because there are no new directories
             being created.  Instead we look for groups with free space if
             the parent directories are nearly full.
b=4466

Description: Network or server problems during mount may cause partially
             mounted clients instead of returning an error.
Details    : The config llog parsing code may overwrite the error return
             code during mount error handling, returning success instead
             of an error.
