Log message:
	bz 359271
	
	A performance optimization for plocks.  This speeds up locks that are
	repeatedly accessed by processes on a single node.  Plocks used by
	processes on multiple nodes work the same way as before.  The
	optimization is disabled by default, and can be enabled by setting
	
	<gfs_controld plock_ownership="1"/>
	
	in cluster.conf, or by starting gfs_controld with "-o1".  It is disabled
	by default because enabling it breaks compatibility with previous
	versions of gfs_controld.  If all nodes in the cluster are running this
	version, then plock_ownership can be enabled.
	
	The plock_ownership mode needs extensive testing.  This also introduces
	some minor changes when plock_ownership is disabled, so new testing is
	also required in that mode.  Abhi and I worked on this together.

	group/gfs_controld: cpg.c lock_dlm.h main.c recover.c 

Log message:
	Significant reworking of how mounts are processed.  The previous
	approach couldn't deal with certain node failures that occured while
	processing a new mounter.  In this new approach, processing a mounter
	is largely independent of processing node failures.  Nodes failing
	while processing a mounter hasn't actually been tested yet, so there
	are sure to be details to fix.
