[lvm-devel] LVM2/daemons/lvmetad lvmetad-client.h Makefile ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	mornfall sourceware org	2011-06-14 02:36:38

Modified files:
	daemons/lvmetad: lvmetad-client.h 
Added files:
	daemons/lvmetad: Makefile lvmetad-core.c testclient.c 

Log message:
	Add a skeleton for lvmetad, a test client, and a temporary Makefile to build
	them. These are currently mostly for testing the daemon-common code. LVMetaD
	functionality is expected to trickle in soon though.
