[dm-devel] multipath-tools/path_priority/pp_alua Makefile ...



CVSROOT:	/cvs/dm
Module name:	multipath-tools
Branch: 	RHEL5_FC6
Changes by:	bmarzins sourceware org	2009-05-06 22:57:58

Modified files:
	path_priority/pp_alua: Makefile rtpg.c spc3.h 

Log message:
	Fix for bz #474451
	Intel wanted a variant of the mpath_prio_alua method to determine priority.
	two binaries are now built out of the alua source. The intel one looks at
	the preffered port bit instead of the asymetric access state bits.
