Hi,

Hi

3. Fix _metadatapercent_disp to not to handle thin volumes



Actually I always planned to 'display' highest_mapped_sector -
so I did now upstreamed it now (as it seemed arg was unused).

So "Meta%" shows what's been the highest written sector as percent.
We do plan to add either switch or new field to show those '%' in
form of byte sizes in future...

Not yet sure how useful or confusing this info is for now...
But i.e. it's interesting to see  how much data is written
by mkfs.ext4/xfs/reiserfs  and how far writes goes on a thin device.

Time for complains...


Following here on myself - after longer debate how this would be
understandable by a user - we've concluded we will rather introduce
a new field and leave  "Meta%" empty - so there will
be rather a new field  'highest_size/HSize' instead.

Regards

Zdenek
