Subject: [PATCH] vdo_stats: Default to 100 % savings for invalid savings

values

We are currently using "-1" when VDO logical_blocks_used is 0
|
|
|
441c7f |
which doesn't match the LVM logic which returns 100 so to make
|
|
|
441c7f |
both values in vdo_info and vdo_stats equal we should return 100
|
|
|
441c7f |
in this case too.
