Subject: [PATCH] vdo_stats: Default to 100 % savings for invalid savings
940a02
 values
940a02
940a02
We are currently using "-1" when VDO logical_blocks_used is 0
940a02
which doesn't match the LVM logic which returns 100 so to make
940a02
both values in vdo_info and vdo_stats equal we should return 100
940a02
in this case too.
