[Cluster-devel] cluster/group/gfs_controld cpg.c



CVSROOT:	/cvs/cluster
Module name:	cluster
Changes by:	teigland sourceware org	2006-11-30 19:48:43

Modified files:
	group/gfs_controld: cpg.c 

Log message:
	From: Steven Dake
	We dispatch in the dispatch handler now instead of saving the
	data.  Also we use dispatch all which will basically try to dispatch all
	messages possible in one go instead of only dispatching on each loop
	through poll.
