[dm-devel] multipath-tools ./multipath.conf.defaults libm ...



CVSROOT:	/cvs/dm
Module name:	multipath-tools
Branch: 	RHEL5_FC6
Changes by:	bmarzins sourceware org	2010-08-24 21:51:10

Modified files:
	.              : multipath.conf.defaults 
	libmultipath   : hwtable.c 
	path_priority/pp_hds_modular: pp_hds_modular.c 

Log message:
	Fix for bz #559852.  mpath_prio_hds_modular can now accept a pathname as well
	as the major:minor.  The default config has been switched to use this.  This
	allows the callout to work even if they can't create any files on /tmp. Not
	Applicable upstream.
