FileStoreSpaceAttributeView#readAttributes("totalSpace") does not return totalSpace

[Rajendra Gutupalli]

Hi Alan,

Spec for FileStoreSpaceAttributeView#readAttributes says 
"totalSpace/usableSpace/unallocatedSpace" can be retrieved by passing 
the respective string parameter, but it does not return as expected.
I just saw the code to see what happening for this input I think 
comparison might be like this.

--  if (attribute.equals("total")) {
++ if (attribute.equals("totalSapce")

Could you please tell me if this is correct.

Thanks
Rajendra.
