[pve-devel] [PATCH manager v3 14/14] fix #6068: ui: utils: calculate and render host memory usage correctly

[Dominik Csapak]

IMHO this and the last patch should be combined, since they don't really
make sense without each other..

one comment inline:

looking at the code, this 'value' seems to be the calculated
'hostmemuse' value, which is calculated by 'calculate_hostmem_usage' and
i don't see how that could ever return a value > 1?
(it basically calculates 'memory' / 'host max memory'  which will always 
be >= 0 and <= 1)

so this change seems wrong to me?
