[bmarzins@sourceware.org <bmarzins@sourceware.org>]

CVSROOT:	/cvs/cluster
Module name:	cluster
Branch: 	RHEL50
Changes by:	bmarzins at sourceware.org	2006-12-18 18:17:45

Modified files:
	gnbd-kernel/src: gnbd.c 

Log message:
	GNBD was hanging with the cfq scheduler, so I changed the default scheduler for
	all gnbd devices to the anticipatory scheduler. This resolves bz #212428
