[dm-devel] multipath-tools libmultipath/dict.c libmultipa ...



CVSROOT:	/cvs/dm
Module name:	multipath-tools
Branch: 	RHEL5_FC6
Changes by:	bmarzins sourceware org	2011-03-18 19:50:41

Modified files:
	libmultipath   : dict.c parser.c 
	multipath      : multipath.conf.redhat 

Log message:
	Fix for bz#675369. Multipath now uses set_value to get the value in all the
	handler functions, and set_value now makes sure that there is value for the
	option before trying to get its length.
