[Xen-devel] [PATCH 1 of 12] libxl: add current_memkb to libxl_dominfo

[stefano.stabellini@xxxxxxxxxxxxx]

currently xcinfo2xlinfo reads tot_pages and uses that data to calculate
max_memkb, while tot_pages is the memory currently used by the domain
and max_pages is the theoretical maximum.
This patch calculates max_memkb from max_pages and introduces
current_memkb to store the current memory usage.
