[lvm-devel] LVM2/lib/report properties.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2010-09-30 14:08:46

Modified files:
	lib/report     : properties.c 

Log message:
	Make generic GET_*_PROPERTY_FN macros and define secondary macro for vg, pv, lv.
	
	Will need similar macros for VG, PV and LV, so define a generic one, and just
	pass in the struct name and variable name for the specific macro.
