CVSROOT: /cvs/lvm2
Module name: LVM2
Changes by: wysochanski at 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.
