[dm-devel] multipath-tools ./multipath.conf.annotated ./m ...



CVSROOT:	/cvs/dm
Module name:	multipath-tools
Branch: 	RHEL4_FC5
Changes by:	bmarzins sourceware org	2009-01-17 00:46:52

Modified files:
	.              : multipath.conf.annotated 
	                 multipath.conf.defaults 
	libmultipath   : dict.c hwtable.c structs.h 
	multipathd     : main.c 

Log message:
	Fixes for bz #214809 and #457228.  Added default configs for hp-sw hardware
	handler and changed max_fds to use max instead of unlimited, since the kernel
	doesn't allow a process to open unlimited fds.
