[dm-devel] multipath-tools kpartx/devmapper.c kpartx/devm ...



CVSROOT:	/cvs/dm
Module name:	multipath-tools
Branch: 	RHEL4_FC5
Changes by:	bmarzins sourceware org	2009-01-19 22:34:02

Modified files:
	kpartx         : devmapper.c devmapper.h gpt.c kpartx.c kpartx.h 
	libmultipath   : parser.c 

Log message:
	Fixes for 455616 and 456457. Make kpartx deal with 64 bit size files, and fix
	the parser issue that makes multipath ignore sections in multipath.conf if
	there isn't a space between the section name and the open brace.
